What an exciting, action-packed, whirlwind, gripping roller coaster meets snorkeling ride I had! And the best part of it: we got a new unit named “UIU”: LEGAL PIRATES! Hurray! Ship ahoy! A crime thriller takes place under the sea! This is original concept and get ready to dive in after wearing your swimming gears!

We have the coolest duo: Solar& McPherson. We’re introduced with them at this first journey and first mission of them and I hope we may read more adventures in near future because I ha

I was a fan of Andrew Mayne’s The Naturalist series, so I was curious about this new series. Given that I have been granted access to book two of the series through netgalley, I picked up this book from audible.
Sloan is a part time officer in the Lauderdale Shores Police force, working as a recovery diver. On a recreational dive in a canal, she surfaces to find the body of a dead woman having just been dumped. As the niece of a convicted drug trafficker, she soon finds hers

Kindle First Read for April 2020!

"Andrew Mayne is an Edgar nominated author, Thriller Award finalist, star of Shark Week and A&E television’s Don’t Trust Andrew Mayne."

Clearly, Andrew Mayne is an international treasure and we must protect him at all costs. And this book sounds incredible.

*Many thanks to the publisher for providing my review copy.

Oh my gosh, have you ever heard of a having a police diver as a main character in a book or series? Sloan McPherson works for Lauderdale Shores PD in Florida as a diver for evidence recovery. One day, instead of evidence, she finds an actual body, and it’s someone with ties to Sloan...

Now Sloan is being watched by an assassin and is racing against a cartel... She only has one person she can trust, the DEA agent who arrested her uncle.

I really loved Sloan as a character. She has secrets and comes

After seeing this recent publication by Andrew Mayne make such a splash across the reviewing platforms, I wanted to have a look for myself. Sloan McPherson has underwater diving in her blood, having grown up with it as her father taught her all there was to know. When she is not contracted out to dive for one of the local police services in Florida, Sloan is scouring the depths on her own. One day while pleasure diving—alone, a major faux pas—Sloan has a body dumped in the water in front of her. ...more
I already knew going into this book that I really liked Andrew Mayne's writing style and his character development. Mayne, never-the-less, surprised me with yet another great thriller, this time set in southern Florida and filled with drug cartels, corrupt politicians, pirates and MORE. Generally I'm not a fan of Florida or water based thriller but from the very first page Mayne had my attention and kept me glued to the pages until the very end. I don't want this to 1 of 2 in a series! I want it ...more

I’ve read all of Andrew Mayne’s book and enjoyed them immensely. One reason I like them is that his lead protagonists are not the usual suspects - detectives, PIs, journalists or ex special forces. Instead we’ve had a computational biologist and a magician, from a long line of magicians, who also happens to be an FBI agent. This book introduces a new character, Sloan McPherson, of the semi-criminal, treasure hunting McPhersons. She is a police officer who specialises in underwater salvage (guns ...more

Check out all of my reviews at:

The Girl Beneath the Sea (Underwater Investigation Unit Book #1) by Andrew Mayne is the start of a new suspense/thriller series featuring a female law enforcement diver. This book has everything I look for in a thriller: a strong protagonist, realistic fast-paced action and continual escalating threats with surprise twists and turns. This book also has the added intensity of being set in the world of professional divers in south Fl
Sloan works as a police diver - a frogman (or frogwoman) as we'd say in the UK. I have no idea if the Americans say the same. She's the one the police call to scrabble around in muddy water looking for knives, guns or bits of dead bodies. And, because she's based in Florida, she's got alligators in a lot of the inland waterways just to keep life more exciting. Sloan's family have a bit of a reputation as pirates and salvagers and her uncle's in prison at the hands of the man - George Solar - who ...more
This was a good thriller. I am a fan of Andrew Maine’s The Naturalist series and I found by comparison this wasn’t as good.

Let me just start off by saying .... what a unique concept. An evidence recovery police diver as the lead character? And, she's female!

I found the first half of the story fairly slow paced but luckily the second half really picked up. I flew through to the end of the book ... was satisfied with the ending. I'm looking forward to the next book, Black Coral.

The Girl Beneath The Sea is the first book in the Underwater Investigation Unit series.

Action-Packed, engaging, and suspenseful!

In this first installment of the Underwater Investigation Unit series, The Girl Beneath the Sea, Mayne has written an adrenaline-pumping tale featuring the intelligent, impulsive, police diver Sloan Harper who inadvertently becomes a suspect and a target when an old childhood acquaintance winds up dead and her family’s disreputable reputation and history as treasure hunters quickly becomes both an asset and a liability.

The writing is sharp and crisp. The

This was a prime first reads and it was excellent. It had all the elements that I love in a book, twists and turns and clues which make you try and guess who did what and to whom.
I read this very quickly as I couldn’t put it down and I wanted to find out who did the crime.

Earlier this year, I read my first book by Andrew Mayne in The Naturalist series, and it is one of the best books I have read this year. This series is qute different from The Naturalist, but just as excellent. I guess I just like Mayne's writing style.

Mayne doesn't waste time on unnecessary descriptions or scenes that slow down the action. Everything happens quickly here, there are many twists and turns and unexpected events. If you like fast-paced thrillers, this is definitely the book for you

Florida is a great setting for a new series by Andrew Mayne, who lets his curiosity lead beneath the sea in a wetsuit. Sloan MacPherson comes from a family of treasure diving rascals, and while pursuing her Phd. in archaeology also has turned her experience as an experienced diver into a career with the Lauderdale force, retrieving sunken bodies as well as such specimens as tossed weapons. Sloan, who also is sharing parenthood with her daughter's father in a relationship she calls "complicated," ...more

Sloan McPherson is a recovery specialist for the Florida police. She hails from a family with a shady background: salvage specialists, who are not above smuggling. Her uncle is in prison. She is trying to make amends, and while diving for work, a dead body is tossed into the water where she is working. Sloan is tough, but takes a lot of risks, especially with a young daughter and an estranged father. For me at least, this plot was highly implausible, and Sloan's miraculous escapes beyond belief. ...more

“Sometimes you don’t get to choose your struggles—they choose you.”

Sloan McPherson has an interesting family. Treasure hunters and drug smugglers and that is just the modern day McPherson's. Sloan has a daughter and she wants something better for her. To that end she is an auxiliary officer for Lauderdale Shores Police Department, a diver for evidence recovery. She is also going to college working on her degree. The story opens when Sloan is on r

Audible reread - this was pretty good as an audiobook too.

Kindle first, you knocked it out of the park! This was thoroughly entertaining! A police diver from a treasure diving family finds herself in the middle of a dangerous search for a hidden half billion dollar stash of drug money.

But that’s not even what’s worth killing for...

Lol, I did have moments of doubt with some of the government conspiracy angles, but they did not bog down the story. Black Coral will be a hard wait.

Well, it’s not The Naturalist, but still so good! What’s also pretty awesome is that last summer I caught the author on the Discovery Channel Shark Week special Andrew Mayne: Ghost Diver, and now I can’t help but wonder how much of his experience doing for that show had ended up influencing this book. Plus I believe I read somewhere that Mayne grew up among scuba divers and law enforcement, so when I first learned about Th

First, a caveat in full disclosure: I met Andrew Mayne when he was a young magician, and we struck up a friendship based on, among other things, the fact that we both wanted to be writers. Flash forward a couple decades after we lost touch, and one of us has written some fifty (?!) books, while the other one of us is a boring lawyer. (Le sigh.) Despite his tremendous success and hugely prolific body of work, I have decided to like Andrew anyway, and I finally got the chance to read one of his bo ...more

I loved this. I found myself holding my breath in several places.
I was glad to see there is another book due out in this series in February. I am looking forward to checking in with this team again.

I found the characters brilliant and really enjoyed the internal chatter of slone.

My one and only gripe was the excessive use of the word interesting.

Wow! Why 4 stars.

It's about:
A young woman underwater diver, who for extra money is a part-time Florida cop in the Everglades FLA diving for guns, bodies, or whatever else is thrown in the water. She gets deeply involved in trying to solve a crime, involving being underwater.

What I liked:
-The main character and a few others were very likable and well developed.
-Most of the underwater stuff was very interesting. Something different. I did not know
This was my first book by Andrew Mayne. This is the first book in a new underwater investigation series. It's told in first person POV by Sloan McPherson, a single mom who is a police diver in Florida. She discovers a dead body in a canal while on an archeology dive. The cops that play these mind games with her to make her out to be the killer, were very unlikable characters. She goes up against these corrupt cops and feds, and I found it very stirring. Sloan is a strong, fearless heroin, and I ...more

Amazon freebie and recommended by my brother who could not put it down. It is just not my favorite kind of story and/or heroine with "rough" edges.
It is just the thing, I suppose, for lovers of diving/boat stuff/weird sub stuff/bad cops/drug cartel ownership of officials/judges VS the little "guy" - or gal, in this case. She makes risky decisions at every turn even though she has a young daughter to keep safe.
There is a second book that I will not be reading.
