Rate this book
1,500 pages of thrilling, suspenseful, addictive romance… and one unforgettable Daddy Dom who would burn the world down for his girl.

When author Emily Martin walks into a kink expo expecting nothing more than a fun day out, the last thing she anticipates is meeting James Logan: a private investigator with the instincts of a wolf and a possessive streak a mile wide. One look, and he knows she’s the one. One touch, and she knows she’s finally home.
Their connection is instant. Their chemistry? Off the charts.
But danger has a way of finding them.

Across these four linked stories, Emily and Logan face deadly threats, unravel complex mysteries, explore exclusive clubs and exotic locations, and learn exactly what it means to build trust, devotion, and an unbreakable bond. From a perilous cruise to the sunny beaches of Mexico, to a chilling chase through New York City after a murderous stalker, every case pushes them deeper into passion… and deeper into danger.
Along the way, they’re joined by a cast of unforgettable characters: friends, rivals, enemies, and allies who bring heart, humor, chaos, and color to Logan and Emily’s world.

Sensual. Emotional. Suspenseful. Addictive.

It was so much fun to revisit the collaring of little kevlar Emmy!
She and her Wolfy Daddy Logan never fail to make me smile.
The collaring was meant to be a small and intimate affair,but they could’ve known everyone wanted to be there for this special moment.
And it was made even more special with all the fun and games leading up to it.
Even Molly,the bed & dungeon’s ghost,had a “hand” in making it an experience to never forget.
And it leaves me in a puddle of warm fuzzy happy.



Of all the Daddies and their littles,Logan and his sweet Emmy are my favorites.....by far!
So,when EJ Frost decided to collect their first three stories in a beautiful boxset,it sounded like a great opportunity to reconnect with them.
And when she very generously gifted me with said boxset,i couldn’t wait to follow them on their journey towards the novella at the end,The Case of the Missing Collar.

And what a journey it is!
I loved them the first time,and i love them even more now.
The care with which Logan handles his little girl,giving her what she needs the most.
Even if it hurts so good at times....
And the joy Emmy brings him in return makes life that much brighter,more fulfilling.
She cares for him when he needs it,giving him every reason to get back into shape when he’s badly hurt.
My reviews of the Casefiles 0,5 to 2 are here:

Logan and Emmy are two halves of a whole,completing eachother,reading eachother without fail.
And nothing says commitment more than a collaring.
They started planning a small ceremony,but friends have a way of inviting themselves.
So,before long there’s a serious number of things to arrange to get everything organized.
The perfect place is at Niagara Falls,a kinky inn called Maid of the Mist.
With it’s own ghost,Molly.
Their host is a direct descendant,and really....Martyn is the perfect host!
He does everything in his power to make their stay a good one.
And it is a great time for all of them,with good food and fun,kinky games for all “ages”
Until the collar disappears....
Will they get it back in time for the ceremony? In one piece?

After this boxset,i am left with a feeling of total bliss.
One that will probably last a while.
The love these two share is so beautiful.
And the friends they gather along the way are so wonderful.
I love them all!!

I've already reviewed book #1 here - https://www.goodreads.com/review/show...

and book #2 here - https://www.goodreads.com/review/show...

but I HAD to know all about Logan and Emily's collaring ceremony - especially after reading Missing Ink - so I borrowed this through KU just for this bonus story alone. EJ Frost has created two incredibly warm, believable characters, in Little Emily and Daddy Logan. Well more than two if you include some of the other Doms and subbies that appear in her stories.


This book had me hooked from start to finish and I loved all of it, well apart from one eeny, weeny tiny thing near the beginning. But that was definitely a me thing and more because it wasn't my kink than anything else. .


It was wonderful to see Emily finally be brave, and relaxed, enough to be her true little age and the way Logan supports her in this was simply amazing. His willingness to dress up in crazy costumes and his pride in how she shone, totally had me falling even more in love with him. He never expects more of Emily than he is willing to give of himself, and his choice of clothing for the collaring ceremony really did emphasise that.


I'm so pleased to know we haven't seen the last of this wonderful pair and their friends yet.

Daddy P.I. 0.5
5 stars

after starting book 1 in this series i wanted to know how emmy and logan met, so i emailed the author and she kindly sent this book to me. for me it makes everything glue together. you get to know the characters inside and out from their first interactions. the back story of this book is a must for me below you sink your teeth into this amazing series. if your into kink or not the murder mystery element will be enough to hold your attention if nothing else. this series will open your mind to a whole new way of thinking. it just gets better and better.

Daddy P.I. 1.0
5stars

When I first started reading this book I wanted to know how Logan and emily met, so I emailed the author and see sent me the prequel and I will say it's a must read, before you start this book. It gives you so much insight into their lives and the dynamics of their would be relationship. This book doesn't disappoint. The whole daddy/little link wasn't something I had read much about.but this book explains and encourages you follow down their path with them. Discovering the highs and lows of a the beginnings of what could be a truly amazing experience or a disastrous life choice. Logan was amazing, gentle and kind. Helping his little girl become who she needed to be, while expanding his own mindset on this kink. Emily was his saving grace in many ways and I cant wait to read more about them. The other characters in the book, really helped built the foundation of this story and I would be great to see a spin off of their own. This was the first book I read by this author and I cant wait for more.

Daddy P.I. 2.0
5 stars

If I could give this book more than 5 stars I could. I loved the prequel, which I felt was a must to help understand some of the parts in book one. I loved book one and I think I loved this one more, if that's possible. Following on from the end of book one, Emmy is nursing Logan back to health. The couple are settling into a new life together, but the past is never far behind them, causing trouble. I find there is a lot of sex scenes in this book, but it is warranted. it helps you learn and understand the bdsm world on another level. The daddy/little dynamic between Emmy and Logan has never been broken down this way in other books I have read with this theme running through it. you get into the minds of all the characters, be they the main characters of the side ones. It's enlightening to see how they all deal with the couple's relationship. The whole scene with Pence, from start to finish was intense. The overall connection between the Doms/Dommes with regards his punishment was out of this world. The fierce-ness of Logan's reaction of Pence's behaviour towards Emmy, had me in the good feels, showing master Logan was a Dom to be messed with. I loved Emmy's quirky nature and her re-wording my a great queen song. I felt sorry for Emmy when the cat fight broke out. Logan not allowing her to defend herself, in book was unfair, but as her Dom he knew how to correct the mistakes which were made by all three of them. If you've already ready the prequel and book one, you know what you're getting yourself into with this series. It will not disappoint. It will only enlighten and entertain your mind. If you haven't read this series and want to see where it leads you, go in with an open mind. No judge calls, as we are all different and have different kinks and this book shows that. It's a really great read and I for one cant wait for the next in this series.

Missing collar - novella
5 stars

It's easy to say this novella will be a 5 stars review from me, before even getting a quarter the way through it. The whole world in which Emmy and Logan inhabit, always makes you feel apart of a great family, when you're reading this author's books. When Emmy is deciding her outfit with the other subbies, the description of it made me want one myself and I loved the fact that professor teddington was styled to accompany Emmy as her fashionista stuffie. The maze scene is thrilling to read. You can feel the excitement in the subbies as the hunters become the predators. As the story unfolds, I keep wishing I was at this amazing spectacular of a weekend, joining in with the ghost gatherings and mad hatter's tea party. The whole picture that was painted in the words of this book just brings it all to life. Great story, wondering ending and I'm waiting for more.

I have found many favorites from reading this series - Logan has joined the group of my favorite male characters, Emily is my first favorite female character(!), and EJ Frost is my newest favorite author. One of the things I loved most about this set of books that tells Logan and Emily's story is that these characters are kind, beautiful souls who will do anything to make the other blissfully happy and they start feeling this way from the very beginning. Even though there are some characters that are so awful and mean to Emily, which made me incredibly sad, it doesn't take anything away from how wonderful these books are. This series also introduced me to a couple of new favorite terms of endearment: angel baby and little wonder. (heart eyes) One of my favorite quotes: "She's wrapped her heart in mines and barbed wire because she's given it before and had it handed back to her in pieces, but once she trusts me completely, she'll be mine."

Beautiful collar.

I didn't think there's a way for me to be drawn more to a couple, but Ej Frost did it. Every book I read in this series feels like Emily is opening up more and more. It amazes me. Logan is so responsive to Emily's wants and needs. The sex scenes feel so real while reading. There is no shame, only absolute acceptance.

What a perfect HFN to end with (until 3.0 comes out! 🤩) and let me say I have never had so many books with so many pages hold so much of my attention for THE ENTIRE TIME. I have never been so sad to see the end of a couple’s story, or so relieved to hear there is actually more coming. Emmy and Logan are my spirit couple and I am so far in love with them. ❤️

So I read this while doing a reread for 3.0. This story is still a bit shocking for me. The things that shock me are what pushes my boundaries in what is exceptable. The author shows me how people who practice the extreme in their lifestyle are not strange, but everyday people who are just a bit different. What makes me love this series is not just the push but the love and friendships that are developed. It's so unconditional (as long as kindness is there) and makes you crave it. So if you want your kink pushed but have lots of HEA, get on this series.

Outstanding

What a terrific book; three stories plus a bonus story, plus bonus information. A brilliant bargain.
Emily is a little looking for a temporary Daddy Dom. Logan is a PI, seeking a submissive to help provide cover for a cruise where he is investigating a death.
The stories lead seamlessly into one another, while being individually satisfying.
Plenty of kink, plenty of sex, and really interesting storylines.
Great characters, well-crafted and engaging.
I'm in love with Emily and Logan. Off to read the next in this series!

Logan and Emily

This box set was 4 books in it. It follows several BDSM couples but Logan and Emily are the two MCs. There are several different BDSM lifestyles in it. This book will have you laughing to tears especially describing the new cat scene that Logan got for Emily. But it also has some parts that bring a tear to your eyes. Very enjoyable weather you read the box set or each book individually.

I love these characters!!

I first read the individual books and really enjoyed them. I figured I'd read the Collection because it contains a story I hadn't read and I'm so glad I did. I really enjoyed revisiting the stories. They are such a no to read. I hope Ms. Frost will give us some more stories about Emily and her Daddy.

Having read PI Daddy 1.0 and 2.0 0.5 and the Case of the Missing Collar rounds out the story I already love! It sets us up for some amazing things in 3.0 and I am so excited for when that book arrives! Logan and Emmy's story is one of the one that will physically hurt when it ends and I hope that never happens.

Nice boxed set

This is the whole beginning of Logan and Emily. They flow easily from one to the next without a hitch.
I think they save each other, love each other so much. This is definitely an X-rated series, so if explicit sex and dominance disturbs you please don't read this!

This collection pulls together all of the stand alone stories showcasing Logan and Emily, and includes the prequel (only available from the author), both Daddy PI stories available on Amazon and a new novella that let's us in on Logan and Emily's collaring ceremony weekend. Basically a smorgasbord of goodness that covers the time period from when they meet to the much anticipated ceremony.

The Daddy PI series is a thoughtful, emotional and steamy DD/lg series with characters that never seem one dimensional. Logan and Emily are flawed, but fully fleshed out and interesting individuals. Their chemistry and growth together is organic, intense and so freakin' magical that great swathes of the book is highlighted in my kindle. Logan is just starting his journey as a Daddy Dom courtesy of Emily, and really, what stands out to me is just how communicative the two are. Whether it is creating a scene together, sharing brutally difficult things about their past or just the minutia of every day, Logan is always thinking about his Emmy and Emmy is always thinking about her Daddy. That thoughtfulness shows in their actions to and for each other.

Of COURSE they face obstacles and struggles on their journey, and some of those issues are doozies. I appreciated how the two of them supported each other and handled things like adults. There was beauty and growth to be found even in the missteps that were taken.

Basically, I love this couple and I love their story. it can be a challenge to keep the relationship fresh in stories where the couple is already established, but I really feel as if this series is just getting started and I can't wait to read more about them and about the secondary characters.

This just goes to show never judge a book on it's cover or title. I should learn my lesson already.. No offense to EJ Frost but I'm not sure I would have picked this up on my own. It turned out that this series has been one of my favorites this month & I can't think of a better title! Book 1.0 was introduced to me in one of my favorite fb book groups & was suggested as a monthly group read. Since book was offered free at the time I figured why not? I freaking loved this story & ended up purchasing the whole set!! Not only was there some heavy play, tons of sexy times, it had some great plots, characters with depth & I could not put it down. I say definitely give Daddy PI a chance! I'm looking forward to reading DirtyGurl's book next! EJ definitely made a new fan. Me! 🖤

Most Authentic BDSM ROMANCE I Ever Read in Fiction

This author has easily become one of my favorite— not just in the BDSM ROMANCE genre— but overall. In my opinion, her stories portray alternate lifestyles more realistically than any other BDSM author I have ever read. Many (if not most) mainstream BDSM ROMANCES tend to be fantasized versions of the real-life thing to be more palatable to a mainstream romance readership, and like soap operas and tele-novellas, everything is perfect until the plot needs it to not be, etc. Everything is clean and tidy.

In these books, no one is perfect. Mistakes are made, some with consequences, some without — with a reminder to the reader that life is not always fair, and that things will not always be equal. Good and evil are not black and white constructs, and the personality types of the characters run the gamete. There are villains who might actually be better people than some of the would-be heroes, which is very real life. Not every jerk met is a villain, and not every “friend” has your best interests at heart.

Often in BDSM ROMANCE, authors skip over the icky stuff. There might keep some uncomfortable elements involved in scene play and showcase emotional vulnerability and offer life dramas, but most romance authors will not dwell overly on real-life “ick” stuff — from bodily functions, to money problems, to disabling injuries, to food and sleep, etc. This author does not shy away from real life moments, which are (I assure you) quite present in everyday alternative lifestyles. Dominants are not perfect people. They also have bad days and moments of weakness. Submissives have bad scenes, accidents, and might be overly punished for something they didn’t deserve. (Like that time my teacher lost my paper and gave me a zero and dropped me a grade even though I know 100% that I did it and handed it in completed and on time.) Life isn’t always fair.

So, if you ever wondered what a real-life 24-7 Power Dynamic might look like, this is probably the closest you’ll get to it without actually living it. While the overall plot/storyline might be fictionally written for entertainment purposes, the portrayal of DD/lg relationship and other BDSM/Fetish/Kink elements in this story are accurate and sound and unashamed. Also, all the BDSM ROMANCE boxes have been ticked as far as healthy BDSM relationships go with CONSENT and SAFE-WORDS and CONTRACTS, and with BOUNDARIES often pushed to the very brink but HARD-LIMITS respected.

This collection includes:

Daddy P.I. Negotiation (Daddy P.I. Casefiles #0.5): https://www.goodreads.com/review/show...

Daddy P.I. (Daddy P.I. Casefiles #1): https://www.goodreads.com/review/show...

Daddy P.I. 2.0 (Daddy P.I. Casefiles #2): https://www.goodreads.com/review/show...

The Case of the Missing Collar: This is the story of the days leading up to Logan and Emily's collaring ceremony. They are at Niagra Falls, staying in a kink-friendly bed-and-breakfast, with a large group of friends to witness and support. They're having a great time with all of their friends, and Logan is especially looking forward to seeing his old commander (chief?), Mac, and his Dom friend Niall (from the cruise). For her part, Emmy is visiting with old friends like Vashti and also Brenna, who is there despite having had oral surgery the day before. The story is a fairly standard pre-wedding tale, complete with a missing collar (thus the title). The twist is that Emmy believes (and I think Logan kinda does too) that . Ultimately, though, this is the story of a couple that we've come to love, who have made it to their long-deserved, hard-won commitment ceremony.
However, there are a few sparkling nuggets: We learn a little more about Logan's ongoing custody issues (just a *tiny* bit more); Mac sees Brenna and is intrigued (Missing Ink); so many costumes and so much playing!

I already had these books in individual format, but the collection is well worth it for the sweet novella alone.

I never NEVER thought I'd enjoy a 'daddy' book or dynamic. But I'm the queen of eating my words on things I swore I'd never enjoy. I definitely enjoyed this. I didn't sleep and gave up shifts at work just to read it. The dynamic was beautiful and respectful and I absolutely loved that she knew about the lifestyle from the beginning. Almost all bdsm books it's them learning or teaching and I am always frustrated and want to get to the experience and knowing part of the story. So it was amazing to dive right into the dynamic with two experienced players and enjoy everything that kind of relationship offered to us.

I loved the story line too. It flowed so beautifully. This author has an incredible talent of building a world to surround you while also creating characters that suck you in and make you either love them, hate them or yearn to know more about them. When the last page came I was so so upset. I never wanted this story to end.
