River Deep

Bitterfrost Thriller #2

by Bryan Gruley

Attorney Devyn Payne is left navigating thin ice as her small-town community fractures in the wake of a shocking crime in River Deep , the second in the Bitterfrost thriller series from Edgar nominee and Pulitzer Prize–winning author Bryan Gruley.

Attorney Devyn Payne expects a quieter life when she returns to her hometown of Bitterfrost. Until the bodies of two eight-month-old boys are pulled from the icy depths of the local river. Was it a tragic accident or something more disturbing?

The twins' distraught parents survived the car crash, but their mother, Catriona Dulaney, was driving. Now she's charged with killing her babies, and her admission of guilt has leaked online. It should be the most straightforward case Devyn prosecutes all year. And yet, to her, it doesn't add up.

With time dwindling ahead of the trial, Detective Garth Klimmek questioning Cat's role in the tragedy, and a suspicious outsider loitering around town, this crime might just be the tip of an iceberg. Devyn's put two Dulaneys behind bars before. This time, whose side will she take―and what will it cost?

This suspense-drenched drama is perfect for fans of Dennis Lehane, the TV show Mayor of Kingstown , and small-town thrillers by Tim Johnston and John Sandford.

About the author

Bryan Gruley's seventh novel, RIVER DEEP, tells the story of Catriona Dulaney, a mother accused of drowning her twin infant sons; Devyn Payne, the attorney who winds up in the middle of Dulaney's case; and Garth Klimmek, the detective investigating the boys' death. William Kent Krueger calls RIVER DEEP "a spellbinding tale of the chaos that engulfs a small Michigan town in the wake of a terrible tragedy. A master of suspense and brilliant architect of the unexpected, Gruley has given readers a topnotch thriller, complete with hockey mania and a glimpse of the best and worst faces of humanity."

Gruley is also the author of the Starvation Lake trilogy, including his Edgar-nominated debut, STARVATION LAKE, as well as two novels set in Bleake Harbor, Michigan. A lifelong journalist, he shared in The Wall Street Journal's Pulitzer Prize for coverage of the 9/11 terrorist attacks. He lives in northern Michigan with his wife, Pam.

[bookcharmedlife · Rating 5 out of 5]

In a small town where secrets run as deep and cold as the Jako River, a devastating tragedy fractures a community and ignites a high-stakes legal battle.

The story centers around Catriona "Cat" Dulaney, a mother accused of the unthinkable: purposely driving her SUV off a bridge, drowning her twin boys. Did a tired mother make the ultimate mistake, or is something more sinister at work? In Bitterfrost, nothing is as it seems. Enemies become allies. Friends become strangers. Can Catriona trust anyone to help her uncover the truth?

As a reader, I find I have a soft spot for small-town stories set in the Midwest, especially if there are secrets to uncover and mysteries to solve. This book fits the mould perfectly. Having hockey serve as a central focus of the community felt very authentic to the storyline. It gave the town a real heartbeat, and a shared passion that contrasted beautifully with the dark crimes unfolding within.

Part legal procedural, part gritty small-town noir, this novel expertly explores grief, corruption, and the thin line between guilt and innocence. Mr. Gruley’s writing flawlessly balances hard-boiled historical grudges with a gripping courtroom drama, keeping readers guessing about the Dulaney family's true motives until the final page.

Bryan Gruley is gaining recognition for his literary works. This is commendable. I was curious about the direction of the story or at least unable to discern it.
It is undoubtedly an engaging read.
I express my gratitude to NetGalley for providing me with the advance copy.

Author Writing Standout
Gruley’s extensive investigative journalism background acts as his greatest literary asset. His prose is sparse, sharp, and deeply realistic, entirely skipping melodramatic thriller twists. His true brilliance shines in his courtroom scene execution, where sharp cross-examinations serve as Shakespearian confessionals that strip away the polite facades of the townspeople to expose generation-old rot.

My Take:
While other reader reviewers are looking purely at the tragedy of the accident, I wanted to point out how masterfully Bryan Gruley uses a leaked interrogation tape to trigger a total structural cable snap across the town of Bitterfrost.

Returning to Bitterfrost after book one feels beautifully familiar yet completely fresh as the plot pivots from hockey culture into a deeply intricate legal puzzle box. The character continuity between defense attorney Devyn Payne and detective Garth Klimmek creates brilliant friction. The procedural focus on how a leaked online confession tape ruins the chain of custody and poisons the local jury pool adds an incredibly realistic, high-stakes wrinkle to the defense strategy.

Gruley proves his mastery of the multi-POV format, taking a town running on max capacity and pushing it straight past its emotional weight limit. It is an absolute must-read that captures the same bruising, small-town emotional trauma found in the works of Dennis Lehane, Tim Johnston, Allen Eskens, and John Hart. (all favs)

Title Significance
The title River Deep references both the physical grave of the Jako River, where the central tragedy occurs, and the subterranean, deeply buried secrets of the Payne and Dulaney families that threaten to drown the community during the trial.

Takeaway
A small-town courtroom is never just about finding legal guilt or innocence; it is an arena where historical sins, societal prejudices, and hidden corruption are systematically litigated.

Why You Should Read
Read this if you enjoy a complex, emotionally demanding legal drama that prioritizes character anatomy, elegant slow-burn pacing, and atmospheric gravity over generic, fast-food plot twists.

"For readers who demand more from crime fiction than standard legal procedurals, RIVER DEEP delivers a masterclass in atmospheric suspense. The frozen Jako River acts as far more than a backdrop; it is an active, chilling force that holds the town's generational trauma. Gruley rejects cheap, sensationalist thriller tropes, choosing instead a patient, slow-burning prose style that focuses deeply on the anatomy of grief and the moral gray areas of small-town justice. It is an engrossing, character-driven legal tragedy that values psychological surety over simple twists."

Author's Note:
I appreciated the author's note, the inspiration behind the novel, and his meticulous research and attention to detail.

💭 My Thoughts
While I thoroughly enjoyed the series debut, Bitterfrost, this sequel represents a massive leap forward into high-end literary fiction. (my fav genre) For readers like me who crave a sharper psychological edge and genuine literary weight, RIVER DEEP hits an absolute sweet spot.

"What elevates River Deep far above standard legal fare is its razor-sharp edge and undeniable literary weight. Gruley doesn’t write comfortable mysteries; he writes crime fiction with a pulse and a blade. Channeling the fierce, atmospheric gravity of Tim Johnston and the brooding, legacy-haunted legal mastery of John Hart, this book presents a world where the stakes are devastating, and no one’s hands are truly clean. It is a slow-burn, beautifully written tragedy that relies on psychological razor blades rather than cheap twists, proving that Gruley has firmly stepped into the upper echelon of modern literary noir."

The narrative architecture beautifully mirrors some of the best legal writers, as Gruley captures that signature dynamic where a defense attorney isn't just fighting a courtroom battle, but is actively suffocating under the local inheritance of her family name. The cross-examinations don’t feel like dry procedural checklists; they read like gritty, high-stakes psychological warfare where no one leaves with clean hands.

Simultaneously, the atmospheric dread shares a striking thematic DNA with Tim Johnston's The Current. The freezing Jako River is an ominous character in its own right, beautifully rendered in sparse, punchy sentences that examine the raw, untidy anatomy of parental grief.

Gruley entirely avoids cheap jump-scares, choosing instead a patient, sentence-by-sentence accumulation of tension that exposes the brutal cost of small-town tribalism, highly reminiscent of Dennis Lehane’s neighborhood-driven tragedies. Also, much like David Joy's literary flair and the unflinching examination of the dark underbelly of small-town communities

What truly cements River Deep as an elite piece of literary suspense, however, is how flawlessly it clicks into the Northwoods noir space mastered by Allen Eskens and Joshua Moehling. In Bitterfrost, Gruley uses the bitter, suffocating winter landscape of icy Michigan elements as a physical manifestation of a community's internal coldness.

Because Gruley brings a real-world investigative sharpness to the page, the story delivers the sophisticated legal and literary suspense action that separates Bryan Gruley’s River Deep from standard, run-of-the-mill thrillers. While the settings differ, these authors hit the same high points: impeccable character anatomy, sharp psychological boundaries, and a refusal to settle for generic tropes. It is a fierce, dark, and elegant legal noir that completely outshines its predecessor.

Verdict
Rating: ⭐⭐⭐⭐⭐ (5 / 5 Stars) — "An Absolute Masterclass in Literary Suspense." A brooding, high-stakes triumph that perfectly balances a sharp procedural edge with deep moral complexity. If you demand crime fiction that elevates the courtroom drama into a haunting work of art, this book is an absolute must-read.

The Final Word:
Bryan Gruley has crafted a towering achievement that stands as a gold standard for literary suspense legal fiction. RIVER DEEP successfully strips away commercial tropes to deliver an uncompromising, fiercely intelligent narrative that values psychological anatomy over cheap thrills. By masterfully executing courtroom cross-examinations as a theater for local exposure, Gruley explores the inescapable cage of family legacy with profound literary weight.

Recs
If you liked the gritty, character-driven tension in RIVER DEEP, read: Down River, The King of Lies, and Redemption Road by John Hart, The Current by Tim Johnston, The Deep Dark Descending by Allen Eskens, A Long Time Gone by Joshua Moehling, Mystic River by Dennis Lehane, or Small Town Sins by Ken Jaworowski.

[Mainlinebooker · Rating 4 out of 5]

Bryan Gruley’s River Deep is a masterclass in slow-burn noir, a novel that eschews cheap shocks and frenetic pacing in favor of something far more enduring: an atmosphere of quiet dread that insinuates itself into the reader’s consciousness and refuses to leave. Rather than relying on the familiar machinery of modern thrillers—rapid-fire twists, cliffhangers, and sensational revelations—Gruley patiently constructs a story whose power lies in its accumulation of tension, moral ambiguity, and emotional complexity.
The novel follows Devyn Payne, who returns to her hometown of Bitterfrost, Michigan, to help care for her ailing mother and ease the burden carried by her brother. A prosecutor by profession, Devyn soon finds herself crossing to the other side of the courtroom when a tragic accident upends the community. A vehicle carrying a mother, her partner, and their eight-month-old twins veers into the water, resulting in the deaths of the children. When authorities begin to suspect that the mother intentionally caused the crash, Devyn steps in as her defense attorney.
What begins as a seemingly straightforward criminal case gradually unfolds into something far more intricate. Hidden resentments, longstanding grudges, and the peculiar dynamics of small-town life rise to the surface as the investigation deepens. Gruley understands that communities often possess long memories, and he deftly explores how old wounds and simmering animosities can shape perceptions of guilt and innocence. In Bitterfrost, facts matter, but so do rumors, prejudices, and the stories people tell themselves about their neighbors.
The novel’s greatest strength is its restraint. Gruley’s prose is lean and economical, free from melodrama or unnecessary ornamentation. Yet beneath that apparent simplicity lies remarkable craftsmanship. Every conversation, every revelation, and every shift in perspective adds another layer to the narrative, creating a steady undercurrent of suspense. The tension does not arrive in dramatic bursts; rather, it builds incrementally, almost imperceptibly, until the reader realizes they have become thoroughly invested in both the mystery and the people caught within it.
There is a confidence to Gruley’s storytelling that feels increasingly rare. He trusts his characters, his setting, and his readers enough to allow the story to unfold at its own measured pace. The result is a novel that delivers not adrenaline but immersion, not spectacle but substance. By the time the final pieces fall into place, the satisfaction comes not from being startled but from seeing a carefully constructed puzzle reveal its full shape.
River Deep will particularly appeal to readers who appreciate crime fiction that prioritizes character, atmosphere, and psychological nuance over relentless action. It is a thoughtful and deeply engaging noir novel that demonstrates how powerful suspense can be when it is allowed to simmer rather than explode. Gruley proves that a story need not race to keep readers turning pages; sometimes the most compelling narratives are the ones that draw us in slowly, then hold us captive long after the final chapter has ended.

River Deep returns us to Bitterfrost, a northern Michigan town that sees its share of shady things. It helps to know that there is a long rivalry between a couple of the families, the Dulaneys and Paynes. The Ice Kings are a local minor league hockey team in a town with a river that separates the community, and well-developed characters who you get to know through Gruley’s careful development.

An award-winning author who has written several other novels, often set in northern Michigan. Gruley’s River Deep is the second novel in the Bitterfrost series. While the focus is on a court case, the battle between the two families, and the struggling Ice Kings, the author’s ability to develop the reader’s relationship with the characters keeps the book in your hands.

The long-lasting battle between the Dulaneys and Paynes creates a backdrop as members of each family are central characters in this second book in the trilogy. Moreover, while most of the novel takes place up north in Bitterfrost, there are some escapades downstate, dealing with some ruffians in the Detroit area. It all comes together and even ties up a few loose ends from the original Bitterfrost novel.

Jimmy Baker plays a smaller role, as well. In a movie version, he might receive consideration as best supporting actor after starring previously. Baker and Devyn Payne are still hanging out together, but can’t decide where this whole thing is going between them. The relationship is a side story to the crazy court case that develops. Devyn is the star in this one — she starts the story as a prosecutor and ends up as a defense attorney in River Deep. The novel focuses on getting things right despite how things may appear.

Garth Klimmek is back as the lead detective who can’t wait to retire. Somewhat gruff, we see a bit more of his character and find out he’s a good man at heart, and that perhaps there is more to Chief Quarton’s story. There are a couple of side characters (Bill Hooper is one) who make the adventure fun. Did I mention that Klimmek has a plan to retire?

The complicated mystery develops, the characters continue to grow, and you won’t be able to put the novel down. You will be wondering if Devlyn and Ronnie (from the Lost Loon Tavern) will end up on good terms again. You’ll want to know what’s up with Devlyn’s mom and what her brother is rounding up as he considers bailing on running the Ice Kings. It’s a minor issue with major potential.

Where will everyone be in novel number three? Gruley sets the stage for the second sequel. Will Detective Klimmek retire? Will he return? We will have to wait and see, but enjoy River Deep! It’s a good read.

A midwest small town with two troubled families with history. Lies, intrigue and deceit abound.
The Jako river feeding Lake Michigan has what on the face of it is the ideal little town of Bitterfrost. Proud of its Hockey team and heading for a big state hockey final that will put the quiet backwater back on the map.
However things are not quite as peaceful as strong undercurrents run through the town and in particular with two prominent families.

It’s hard to think of a worse scenario, a mother and her husband are in the habit of taking their new-born twins for a ride in their pick-up to calm them and send them to sleep. The twins mum ,Cat, worse nightmare begins when the car goes off the road and into the Jako River. The parents survive and are helped to shore by a mysterious man wearing an eyepatch. The twins are not so lucky and are drowned still strapped to their seats. Worse still Cat is a known drunk and is tested positive for booze. She is arrested
and charged with two counts of 1st degree murder and the attempted murder of her husband! An apparent confession to the crime seals her fate and Cat is resigned to a life sentence without parole. In her grief she believes she deserves it.
Up steps her lifelong enemy Devyn Payne who is convinced that the confession was wrongly obtained and is ambiguous at best. Devyn quits as prosecting attorney and crosses to the defence team. Cat resists as she is in self pity and the last person around her is her enemy!
There follows a twisting tale of lies and deceit from big monied companies with bottomless funds, intrigue involving secret mistresses and more lies.
Cat is a troubled soul with issues with the booze but you can’t help gunning for her. Devyn is also a great character with a strong will, and together the story bowls along at a
pace

Gratitude to NetGalley and Joffe Books for the ARC.

Given his pedigree, it is probably inappropriate for me to say that Bryan Gruley can write. Let's just say that after reading “River Deep”, my first encounter with his work, I am convinced that I want to read more of what he has written, particularly the first book in this series, and whatever comes next.

If, like me, you have not read the previous installment, don't let that stop you. “River Deep” works perfectly well as a stand-alone novel. That said, based on the quality of this one, starting from the beginning would hardly be a mistake.

This is a dark book. It opens with tragedy and rarely strays far from it. Yet what impressed me most was not the mystery itself, but the way the story is told. In fact, it is difficult to pin the novel neatly into a single genre. It contains elements of crime fiction, legal thriller, and family drama, but ultimately it succeeds because of its storytelling rather than its classification.

I was surprised to discover that the novel contains exactly one hundred chapters. For a book of roughly 360 pages, that sounds excessive. Yet the structure works remarkably well. The short chapters, shifting perspectives and developments, and steady pacing create momentum and keep the reader engaged throughout.

The result is a novel where the mystery matters, but the people, their choices, and the consequences of those choices matter more. “River Deep” reminded me that a great novel does not have to reinvent its genre. Sometimes it simply needs to tell its story exceptionally well. Bryan Gruley does exactly that.

Five stars, and a new author added to my must-read list.

[Scott Nickels · Rating 5 out of 5]

River Deep is the latest novel by one of my favorite authors actively writing in America here in 2026. I don’t wish to pigeonhole his work as mystery fiction, nor is it legal fiction. As James Lee Burke elevates his mystery and detective novels above the genre so does Bryan Gruley with his stories. So River Deep is his second book in his latest series ( May it be number 2 of several!) centered in-and-around Bitterfrost, an aptly named small town in the northern part of Lower Michigan. In River Deep we reconnect with Devyn Payne, who returned to her hometown in the first book (Bitterfrost) in the series.
This book explores, via a seemingly straightforward tragedy, perhaps whether it really was a crime. It delves into the moral ambiguities, the searing pain of family loss, with large helpings of deceit, loyalty, and love. Plus the reader gets a great courtroom drama. This book works fine as a standalone story; however, Mr. Gruley deftly intertwines key characters from the previous book. So if you pick up “Bitterfrost” it improves “River Deep.”
Probably not going to be a surprise, but thanks to NetGalley for this 5-Star best read of 2026. (I know it’s only late March but allow me the extravagance.)

Catriona Dulaney has been drinking. Her car plunges into the Jako River and, barely alive, she is dragged to safety by her husband and and a mysterious stranger. Her 8 month old twins drown, trapped their car seats. The Dulaney family is notorious in the hockey town of Bitterfrost and, after Cat confesses, she is arrested for the murder of her children.

Attorney Devyn Payne has returned to Bitterfrost to care for her mother, who is in the early stages of dementia. The prosecutor assigns her the case, expecting it be will be a slam dunk. But Bitterfrost is full of secrets and what appears to be and open and shut case will lead to murder, threats and the unexpected.

Bryan Gruley, an Edgar award nominated and Pulitzer Prize winning author, has delivered a novel that is heartbreaking and suspenseful. River Deep is a tour-de-force. Dark and atmospheric, it blends police procedural with mystery and family drama. Cat Dulaney is a tragic figure, full of grief who wants to fight the world. How can she trust Devyn, the woman who sent her two uncles to prison and is indirectly responsible for her father’s death? The issues in River Deep will stay with you long after the final pages. 5 stars.

River Deep by Brian Gruley is as interesting as any novel this reviewer has read in quite some time. Add to that the going on of a minor league hockey team, and you have a setting that will have readers asking for more.
River Deep is the second in a series set in northern Michigan. Much of the action focuses on a court case between two families with a long, contentious history and on the aforementioned Ice Kings, the minor league hockey team. Some of the action takes place in Detroit; however, the majority occurs in northern Michigan. Many of the old players are back from the first novel, and the lead detective is like so many law-enforcement personnel, burned out and ready to retire. Many subplots and sidebars will keep the pages turning. Numerous questions remain unresolved and may not be answered unless this talented writer produces a third book in the Bitter Frost series. Whether there is a third entry in this intriguing and twisty series or not, readers will enjoy Bitter Frost. Though this book can be read as a standalone, readers will benefit by reading the first in the series. Not only will it increase familiarity with the characters, but it will also open their eyes to how talented and wonderful a storyteller the writer truly is.

[Dan Brink · Rating 5 out of 5]

I love a good mystery, and Bryan Gruley never fails to write just what keeps me hooked from the very first to the very last paragraphs of his books. From Bleak Harbor to Starvation Lake, and now Bitter Frost, the familiar, interesting, well-written characters and places just keep coming.

In River Deep two prominent families in Bitterfrost, both with an axe to grind, meet again in this deep, dark tale. Catronia Dulaney, Devyn Payne, Garth Climmeck, Jimmy Baker, beer-league hockey, the Bitterfrost IceKings, Big Henry’s and the Lost Loon Tavern and, of course, Zelda the Zamboni, play a part in this crime drama set in a small Northern Michigan community. Family relationships, shady local business dealings and politics, and small-town life all meet in this telling of the tragedy on the banks of the Jako River on a cold winter night in Bitterfrost.

Bryan knows Northern Michigan, and those of us who live here recognize, in his books, the kinds of people and the kinds of places that are real everyday parts of our lives.

If you like a good mystery, I highly recommend any and all of Bryan's books.

Attorney Devyn Payne has decided to stay in her home and take a job as a prosecutor, despite her experience as a defense attorney. But then she faces the toughest situation you could imagine. Two 8-month-old boys die when the car their mother is driving plunges into the local river. Was this the actions of a desperate mother or purely an accident? And there is another possibility. Did someone else cause the accident?

This is a tough case with the subject matter at hand. Quite emotional. And then you add to it the dilemma of what if you get this one wrong.

Bryan Gruley is an exceptional writer. This is one of those books you absolutely do not want to put down at all. You want to find out what happens next. And the reactions of the different characters to all of the developments that take place throughout the investigation and trial. Just so well written. This novel is special. Thank you, Mr. Gruley.

Bryan gave me an advanced copy of River Deep at the Boozy Book Fair in Charlevoix. I loved the novel! Gurley’s River Deep is a fast-paced thriller reminiscent of a William Kent Kruger mystery. From the opening pages, the tension snaps tight and stays that way, driven by Gurley’s sharp pacing and his gift for weaving multiple storylines into a single, propulsive current.
What truly elevates the novel is the character work—especially his women, who are written with nuance, grit, and emotional intelligence. Gruley also brings Northern Michigan to life with the authority of a local. The woods, water, backroads, and tight knit communities aren’t just backdrop—they shape the stakes, the secrets, and the people who carry them.
Add in unexpected plot twists that land cleanly and never feel cheap, and River Deep becomes that delicious thriller that satisfies both the adrenaline seeker and the reader who wants characters with depth and heart. Great read for insomniacs! This would be a good choice for a book club. I'm recommending it to mine.

[Gatorman · Rating 3 out of 5]

Pretty good read from Gruley featuring Devyn and Jimmy again which suffers from some very silly setups. Having an assistant prosecutor switch to the defense side right before the trial is absurd and not believable at all. In addition, the trial scenes are very cartoonish and over the top, draining the story of the dramatic effect Gruley may have been going for. Still, I enjoy the characters, and the basic plot of why Catriona drove her two little boys into the river kept me intrigued. I've read all of Gruley's novels and I wish he'd go back to the edgy, darker style of his earlier books. The hockey scene is always a plus, and it's well-written, which earns marks. I'll keep reading what he puts out, but I'll hold out hope that it goes back to the style of the first series. Recommended for fans of the genre. Thanks to the publisher via Netgalley for the free ARC in exchange for an honest review.

This is the second in the series. I haven't read the first but it didn't make any difference. It starts with a car going into the river Jako resulting in the death of two babies. The mother and her husband manage to escape and the mother is immediately charged with the deaths of the children.

I loved the small town vibe here with half the town in Cat's camp declaring her innocent while the others see her as a killer. She has not done herself any favours but a further murder raises more questions. There is some organised crime involvement in the background along with an ex state trooper so there's a lot going on here. The main character Devyn is a very likeable character. Along with the storyline that will guarantee to have you hooked, the whole character set is very well done. The legal scenes were also riveting so this book really has a bit of everything. As for the twist at the end, all I can say is wow! I will definitely look out for more in this series.

[Trish · Rating 4 out of 5]

This is the second book in the Bitterfrost hockey thriller series, and after loving the first one so much, I think I expected this sequel to be a lot more hockey focused than it was. Hockey is still part of the story, but not nearly as much as I wanted, which was a bit of a letdown for me. The main storyline still makes this one a fun read, though. The middle dragged in a few spots, but I really enjoyed the way everything came together at the end. I’m also very curious to see what kind of shenanigans Devyn Payne and Jimmy Baker get into in book three because I absolutely love their characters. I’d definitely recommend this series for fans of hockey and legal thrillers. Even if you haven’t read the first book, you can follow along just fine, but I highly recommend picking up Bitterfrost first because it’s so damn good.

River Deep delivers an excellent written, slow burn, suspenseful, crime mystery. This story is told from multiple points of view with excellent character building! Set in a small town with rival families, a tragedy occurs in the middle of the night. Is it an accident or is it murder? Who is involved and what are their motives? You must keep reading to find out! The chapters are short with each chapter being told from a different characters point of view, building a well rounded story. The more you learn, the more you will question everything you thought you knew.

In a seemingly straight-forward case, Bitterfrost resident Catriona Dulaney is accused of driving her family car into the freezing Jako River, killing her 8-month twin sons. But the Dulenay family are a dangerous family in the area and there are plenty of secrets to hide. Attiorney Devyn Payne has returned to Bitterfrost and Catriona's case is the first one she will be acting as prosecutor. She had already put 2 Dulaney family members in prison last year. But Devyn abruptly changes her mind and decides to work for Catriona's defense team.

Detective Garth Klimmek just wants to close this tragic case before retiring from the job. But a strange man lurking in the outskirts may provide the key to the truth.

This was a gripping entry in the Bitterfrost thriller series.

A riveting tale of the events following a tragic drowning of two infants who were trapped in their parents’ vehicle in the river near their home, whilst the adults escaped.

Whilst the second in the author’s series set in the town of Bitterfrost in Michigan, it reads very well as a standalone book.

The various characters and their personalities, together with the way in which the investigation and the strands of the story are interwoven makes for a fascinating tale despite the horrific circumstances in which it is set.

I plan to ensure that I read its predecessor and any further thrillers in the series.

A Good Read

Parents of 8 month old twin boys, Catriona and Sammie, were in the habit of taking the babies for a drive when they wouldn't settle at night, but one evening the worst thing in the world happened. The car ended up in the lake and Catriona was driving. The parents survived, the babies didn't and Catriona was arrested. Prosecutor Devyn Payne does not believe it was deliberate and decides to change sides and act as Catriona's defence lawyer. It took me a while to get into this book but once I did I found it a good read.

I missed the first novel in the Bitterfrost series (entitled “Bitterfrost”). If you are like me, don’t worry, there is not a steep learning curve in “River Deep”. You will be caught up fairly quickly. However, after reading “River Deep”, you will be dying to read “Bitterfrost” mainly because you won’t be ready to let go of these characters. It’s that good.

Attorney Devyn Payne has decided to stay in her home and take a job as a prosecutor, despite her experience as a defense attorney. But then she faces the toughest situation you could imagine. Two 8-month-old boys die when the car their mother is driving plunges into the local river. Was this the actions of a desperate mother or purely an accident? And there is another possibility. Did someone else cause the accident?

This is a tough case with the subject matter at hand. Quite emotional. And then you add to it the dilemma of what if you get this one wrong.

Bryan Gruley is an exceptional writer. This is one of those books you absolutely do not want to put down at all. You want to find out what happens next. And the reactions of the different characters to all of the developments that take place throughout the investigation and trial. Just so well written. This novel is special. Thank you, Mr. Gruley.

River Deep nails the icy Midwest noir atmosphere. Gruley can make Michigan’s wind cut straight through a summer heatwave, but the story itself gets bogged down in repetition, tangents, and half answers that feel more evasive than mysterious. The plot finally wakes up in the last stretch (a bullet helps), but the slow drag to get there left me more exhausted than intrigued.

Atmospheric, yes. Cohesive and compelling? Not quite this time.

The second installment of the Bitterfrost series was every bit as compelling as the first, and I'm already looking forward to the next book.

The story centers on two families in a small Michigan town who have been at odds for generations. So when Catriona Dulaney is accused of killing her sons, it's no surprise that she's wary when Devyn Payne steps up to defend her.

Family dynamics and hockey serve as constant backdrops throughout the novel.

This is a fabulous book. It captures Northern Michigan perfectly. The description of real locations woven with fictional characters makes reading the book interesting. While the storyline takes many twists and turns, I followed it easily and kept the pages turning late into the night. I am now anxiously waiting for what I hope is a third book in the series.

Found out after I started this book that it’s the second installment a series. As such, the characters were introduced but not as fully as I’m sure they were in the first installment. After I got started though the story was engaging and had twists and turns I didn’t expect. Now I just need to go read the first one!
I’d like to thank Joffe Books for the opportunity to read and review this book.

Decent second installment of crime in Bitterfrost, MI. A mother, father and two babies go off of the road. Babies don’t make it and mother is assumed to be the guilty party. But is she? A few twists and turns make the story interesting.

This was my first book that I read by this author. Fast pace mystery. I would read more by him.

WOWW was this fun. The mystery was dynamic, the murders kept coming, and the detectives + lawyers working on the case provided such a fantastic story. I wish there were fewer perspectives, but I really enjoyed the court case and final twist.
