Times are changing in West Newton, and the game is finally up for Firearms Officers Taylor Campbell and John-Paul Ateba. After pissing off HR one too many times, they find themselves re-assigned to the sleepy retirement town of Dingly Heath, where the only lineup is outside the supermarket when incontinence pads are on special offer.

Except, there’s something not quite right about the locals, or their soon to be colleagues, or the place that was once crowned ‘Britain’s Most Motivated Town’. Soon, Johnny and Taylor discover that something much darker is lurking beneath the pristine lawns and show-stopping hanging baskets, and that they may have accidentally planted themselves in the heart of the growing alpha/omega unrest.

Best friends since childhood, the new assignment will push their friendship beyond its limits, especially when one of them has been secretly in love with the other for over a decade.

This is a childhood best friends-to-lovers, M/M, alpha/alpha omegaverse novel.

CW: descriptions of past child abuse (neglect, non-sexual), violence, explicit sexual scenes, explicit language, dark Brit-cop humour, an implied eating disorder (binge eating), unhealthy codependency between MCs, taking the piss out of one of the MCs religion (Christianity). Note: One of the MCs is heavily ADHD-coded and experiences all the difficulties that come with that neurodevelopmental disorder. Mpreg is a part of this world but does not feature heavily in this book.

The Omegaverse Case Files series by @c.t.whistle just keeps getting BETTER AND BETTER. Y’all, Lock Step was a DELIGHT. Johnny and Taylor’s story had idiots to lovers detectives (well, they get sort of a demotion in this one 😂 but it all works out), all the YEARNING, but also….. it’s alpha/alpha 😮‍💨, there’s TONS of scenting, biting, alpha posturing, pacing, “touch him and ☠️” UNGHHHHHH it’s so good.

Something I love in CT Whistles books is how “wolfy” her shifters are - they spend a good bit of time hanging out shifted, and I LOVE all the scenes where Johnny and Taylor wrestle and run together as wolves, together AND with Johnny’s WONDERFUL family. The found family/pack vibes are IMMACULATE in the series and this book.

Another fun thing that’s been in every single one of CT Whistle’s book is a 🥵🥵 car sëx scene, and omg, they are all amazing but this one takes the cake I think. None of these guys can ever wait to get home 🫠😂.

If you like omegaverse, shifter romance, detective novels, or just FREAKING AMAZING mm romance books, you need to start this series IMMEDIATELY. I’ve DEVOURED every one!

It took some effort to finish this book—and honestly, by the 60% mark, I started skimming a bit.

I really liked the first book, the second one was good but a bit more meh, and this third one was just... meh. I was bored. And sadly, I wasn’t really into Taylor and Johnny as a couple, not as much as I would have liked to be (I love friends-to-lovers trope). It took a while before I saw any chemistry between them.

The plot of the book didn't interest me at all and some things I didn’t enjoy, but there was a lot of good here as well. Taylor and Johnny’s relationship developed nicely (after the boring start), and I wanted to read all their scenes. There were definitely some sweet, funny and steamy moments between them, and I really liked the ending. I also loved how Taylor was able to heal his inner child a bit by helping William. I also appreciate all the different, unique characters in this book series.

What I didn't enjoy:
If I pick up a childhood friends-to-lovers Omegaverse book, I don't want to read about casual threesomes, bunch of retirees (some of whom act horny), wrinkled tits, shit (literal shit), bad smells, and perverts who touch themselves in public places 😀 I mean, this book clearly attempted to adopt a certain kind of humorous approach, but I guess the humor in this one wasn't really my cup of tea. I don't think I would have paid that much attention to it if the overall experience had been better, but because I was a bit done with the book already, those things certainly didn't help matters 😂 And in addition to this, if the couple's banter and inner monologue goes like this:

“Sure. No worries. I’ll just go back to sniffing your dirty underwear.”
”You better be fucking joking.”
“Someone’s gotta tell you to start upping your fibre intake.”
”You filthy bastard.”

’Johnny was panting. Quietly. Shamelessly.
Understanding now why his parents had their room on the ground floor, away from everyone else.
Ew, fuck.’

Eeehh…

In conclusion; I'm not saying the book is bad (therefore 3⭐️) but unfortunately, this one just wasn’t my favorite.

The first book on this series impressed me. It was a very well written story from a genre I’ve come to not expect much.

The second book was overall disappointing, I liked parts of it.

Now this third installment just instantly put me off. Gross humor (I’m not kidding, the first few pages really wanted to drive the point home with unnecessarily off-putting details), and a main character that’s supposed to be “ADHD coded” acting like an idiot. Not my cup of tea, I will pass.

Wow better than I expected! I love some alpha-alpha pairing but the brother background could have made me pause. Luckily it wasn't an issue. I liked the mating instinct and the scent marking. The wider family was great to meet as well. I think this could be my favorite one so far! The author seems to get more skilled with each book.

Did I love this book and the characters? YES!

Was it "safe"? A big ole NOPE!

I don't know how the author wrote such beautiful compelling characters while also including a multitude of things that often make me throw my kindle away in disgust. But, they did. Seriously... so good. The one star off is for the list of terrible things that this author included that I don't tend to like.

1. VERY promiscuous main characters. Especially Taylor. They are known for sleeping with everyone at their old station.

2. Bad behavior that doesn't seem to get addressed. Taylor has ADHD and some intense anger issues. He also seems to not be able to regulate his emotions at all. Johnny does a lot of the emotional labor to try to keep Taylor acting somewhat sane. While Taylor was loveable and he seems to have found his place in the world, there is no acknowledgement of the real harm he does by acting so badly. Both of them would sleep on the job, sleep with colleagues, screw around, do pranks, etc. It was not cool. Frankly, Taylor probably needed a lot of therapy and mental health work and possibly medication.

3. Friends to lovers where one of them has been pining the WHOLE time. Johnny has loved Taylor since they first met. And, instead of ever saying anything, he's followed Taylor into a career he doesn't really like, done a lot of stupid stuff with Taylor, and lied about his truth. To the point that Taylor doesn't realize certain things about Johnny because he hid them from Taylor their whole friendship. That's not great.

4. They sleep with other people, including an on-page shared lover situation. The only thing that made this okay for me is that the 3rd person agreed to it and orchestrated it to get his and get them together. It was still pretty skeevy.

But... I will always read books by this author because they write so well and I love it all. Some authors can throw in total crap behavior and I still love the characters and the story. Who knew!?

What a complete unicorn of a series—MM, ABO, shifter mystery romances that are focused on social welfare and inequity. As a social worker and compulsive MM romance reader, this series feels like a gift from the universe. I also appreciated CT Whistle’s autobiographical statement at the end of this installment—hi comrade! I feel the exact same way about the reading of and sometimes the writing of romance as a foil for work.

It’s funny how a mystery involving the endangerment of senior citizens and child welfare can simultaneously almost be a cozy to some degree. Taylor and Johnny are so completely at home in each other’s lives that there’s a slow intimacy that permeates the book from the get go. It’s a beautiful thing, though my brain wasn’t sure what to make of the first little bit—they were pretty much an established couple before the book started if not for their mutual insecurities. Some ABO authors make a big deal of the taboo of relationships between alphas—Leta Blake’s awesome ABO series has a really angsty book focused on this dynamic—but CT chooses to forgo this plot device. I think I kinda wanted that to be a thing as a more solid reason why it took Taylor and Johnny to see what was obvious to everyone else who knew them, but that’s a completely subjective opinion and didn’t take away from the quality of the story itself.

Anyway, I can’t wait for more from this author, though I understand why it might take some time between volumes. Added extra glitter sparkle bonus points for the fantastic cover which doesn’t stereotype what we romance readers want from a book. I wish more romance publishers/authors etc didn’t feel the need to put overly salacious covers their products.

I enjoyed overall, but not nearly as much as the first two books, and almost DNF'd a couple of times. The author mentions in the beginning notes that one of the MCs has what is clearly undiagnosed ADHD and that it may make for a frustrating experience, and that was certainly the case for me. Particularly because nobody around him seems to recognize that he is struggling in a way that he should be seeking help for, and thus he makes zero moves to go to therapy, seek medical help etc. And while that is probably realistic considering he's an alpha (literally) male in law enforcement, it was difficult to be in his head for the whole book, see him continuously make poor choices, and then have him really make no progress in getting help.

The relationship here was sweet, and I understand the decision to do the best friends to lovers trope with the alpha/alpha pair, but it did feel like it was lacking a bit of the real tension I prefer in my pairings. IDK, I still enjoyed the writing overall, I liked that characters and cases from the previous books were woven throughout in a way that felt very natural, but this one just didn't resonate with me as much as the first two, and TBH, I'm not particularly interested in the next pairing, but I'll probably still read.

DNF @20%

Quite honestly I'm just bored. This isn't as addicting as the first two books in the series was. I also don't usually prefer alphaxalpha pairings. There are exceptions of course but this one is just not really doing it for me. I don't think this was a bad book per se, just not a book for me, and that's okay.

3.5 stars for this one from me.

Although I truly do love this series (especially book 1), it was harder for me to connect with this installment. I think my biggest reason for this was Taylor’s character and his choices. Laughing off that his “usual MO” was sleeping with married people just was a huge ick for me especially since it obviously something he did frequently. Also, the VERY detailed threesome really was not my cup of tea for a book with a romance between 2 people.

I really liked Johnny’s character though and enjoyed the found family aspects of this book.

I’m very much looking forward to the next book and seeing where the plot goes!

ARC Review

My excitement to read this book was extremely high. Like, really high. So I was really worried that it wouldn’t live up to my expectations. I loved Hammer & Gavel and Night Call so much that I was worried that Lock Step wouldn’t live up.
Well, those concerns were unfounded. Lock Step did not disappoint. CT Whistle is so damn good at character development and world building. I am living in Dingly Heath in my mind.
Then there’s our main characters. I see myself in both JP and Taylor so you know I was rooting for these two. I love stories with imperfect characters who are good people at their core and that’s what each of these books are filled with. Great characters that grow and learn about themselves and become better people for and because of someone who changed their perspective about life and/or love.
Plus solving crimes?! Best of all worlds!

2 stars - I’m so disappointed!! I have LOVED the other two books in this series and this one just was not it.

This is alpha/alpha, long-time best friends discovering true feelings and a couple of first-timers having a go. Also a very nerve-grinding character who is hellbent on making terrible choices. Just no.

This didn’t work for me at all. These two guys are possibly perfect for each other because Taylor lashes out and JP fixes it. I love me some co-dependent toxicity but this story was just a few marks left of center.

The Reno 911 feel of Dingly Heath was cute at first and then got kind of boring. I forced myself not to skim this one.

Their relationship was drawn out for no reason. Miscommunication or refusal to communicate gets on my nerves. A well-placed conversation would’ve taken 100 pages off this story.

JPs family was a central element here because the main relationship between he and Taylor was a nothing burger. The pages had to be filled with something I guess.

Overall, I think Taylor was my main issue. He was off-putting to me and I didn’t like reading his perspective. He was funny at times I guess but only when he was making things difficult for someone else.

I hope the next one is back to the standard of top-notch Omegaverse this series was before this book. The 4th one is about two omegas so that’ll probably be my jam.

Fun best friends to lovers, werewolf romance!

Y'all this book was so much fun! Johnny and Taylor are best friends who live and work together. They're so codependent and honestly kind of a mess. But there's something so endearing about them that you can't help but root for them. I thought we'd go on a journey and watch them fall for each other, but though I was a little surprised to find out that Johnny has been in love with Taylor for years, it makes sense that these two have been head over heels for each other forever.

It takes a little longer for Taylor to acknowledge his feelings (he really needed that threesome to figure things out), but even before that it's clear that his love for JP surpasses all others. They know each other better than they know themselves and are always there to give each other exactly what they need.

I also loved their relationship with their pack/family. The kids were honestly one of my favorite parts and I loved how involved JP and Taylor were in their lives. They're so protective and the moments we get to see them as wolves and as a pack were so special. It really emphasized the bond they share, with each other, and with their pack.

And I can't end this without mentioning their work crew! Isla, Amil and Wendy were such great additions to this series and I'm so excited for Amil's book next. I also have to mention the relationship Taylor built with William. The way Taylor saw himself in Will and took him under his wing was so beautiful and I just love that Will was able to find the care he'd been missing all his life.

JP and Taylor took us on quite the adventure. They're loyal and protective and love so deeply. From nail polish therapy to sharing clothes to their overprotective natures, I really enjoyed seeing them find their way to a HEA!

"It was easy to accept love when all you’d ever known was love."

alpha/alpha omegaverse owns my entire heart!!!

i literally had the release of this book marked on my calendar, i was so looking forward to it! and it did not disappoint, this was a near perfect follow up to this fun series and it had everything from mistery, to action, to steam and all the yummyness you should expect. it was fun, and sexy and made emotional multiple times.

taylor and jp were the dumb and dumber after my entire heart and all the found family vibes were to absolute die for, just a really good time all around.

C.T Whistle has me as an eager reader, ready to goble up anything and everything they publish going foward; Hammer & Gavel and Night Call: Book 2 of the Omegaverse Case Files had already hooked me, but this third installment just brought me so much joy during one of my biggest reading slumps in recent years and i'm very grateful for it.

Cute story for this series, we got a new town filled with querky elderly folk, a whole new team and an awesome family pack.

I would say it was more easy going in this book than the others. Slower paced and we really pulled into the small country town life, found family and the dynamic between two alphas more so than the crime.

Fair warning going into this there is a threesome with the two main characters and a stranger from the resturant, if you dont like that kind of thing. I normally dont but i didnt mind it here as it was very clear the third knew they were seperate and encouraged it so that John-Paul and Taylor could explore the possibility of 'them' without pressure.

Also appreciate the authors note at the end explaining that they work in full time social care and thats where the characteristic for some characters come from and that they wanted to write a HEA for people who dont get them in real life. My hat of to you C. T. Whistle, I full heartedly thank you for doing the job that can be so frustrating and heartbreaking.

This book was incredible. I adored these boys and loved every second of watching them find themselves, each other, and their place in the world. It was such a satisfying read and probably my favourite of the three. I loved the community and family Whistle created here, and can't wait to see what is in store next for us.

I requested an ARC of this book, with the only stipulation that I write an honest review.

It is a lovely story of childhood friends to lovers, with so much pining! As the MCs’ relationship changes, we see their growth and development. From being side characters in previous books, a change of environment allows them to get their own HEA. As always with C T Whistle, some social issues are explored as key themes - in this book, this includes nature v nurture in childhood; as well as growing old.

4.5/5. At first I was like ehhh, but the more I read, the more I was like ahhh. Like, this one. This one is the move. By far my favourite of the series. And I don’t know why anyone would have difficulty rooting for Taylor. He’s fucking great. Broken, but in a way that you can tell his cracks have been repaired with gold, and JP is for sure the one who filled them all in. ADHD is never a reason to not love someone, it just means you know who means that shit at the end of every chaotic day. The growth and healing were immaculate. I fucking cheered so hard for the two silly geese, and the new satellite characters gave until they couldn’t give anymore, and then kept giving. Fuck. This one . 🤌
