The Deep Scuba Novel Series: Deep Shadow

A Review of the Caribbean Action-Adventure Thriller Deep Shadow

I love a good book almost as much as I love scuba diving and adventuring. So when I stumble across a compelling book series that ticks all three of those boxes, I can’t help but review and promote it!

The Book: Deep Shadow

“Scuba divers travel from all over the world to visit the little island of Bonaire, with its crystal-clear waters and a host of beautiful marine life. After three years in the “Divers Paradise”, divemaster Boone Fischer thought he’d seen it all; but on a routine afternoon dive, he spots something that will turn his tranquil life upside down.

From the arid shores of the ABC Islands to the tropical jungles of Venezuela—from the ocean depths of the Southern Caribbean, to the lush islands of the Northern Leewards, Deep Shadow takes Boone and the reader on an action-packed adventure filled with danger and suspense.”

The Author: Nick Sullivan

Nick Sullivan is an author, actor, narrator and avid scuba diver. Born in East Tennessee, he’s spent the bulk of his adult life in New York City, working in theater, television, film and audiobooks. After recording hundreds of books over the last twenty years, Nick decided to write his own novel.

The Deep Series (formerly “Caribbean Dive Adventures”) is a succession of books inspired by decades of scuba travel. The first book Deep Shadow is set in Bonaire, the second on the little Dutch island of Saba and the thirds and fourth focusing on Caye Caulker, Belize and Cozumel, Mexico respectively.

Although Nick still lives in New York City, he tried to sneak off to the Caribbean every chance he gets.

It’s been a really long time since I’ve read a book that I’ve had a hard time putting down. I’m talking – Harry Potter and the Hunger Games books kind of long time. And while I know submarines and scuba suits are a far cry from the magical world of Hogwarts, Deep Shadow was a novel that both impressed and surprised me.

Deep Shadow is an intriguing and easy read – one that I would highly recommend to any adventure, thriller and mystery-loving enthusiast. This book was a perfect blend of Anthony Horowitz meets James Patterson meets Jacques Cousteau. It had a fast pace and high-energy plot that flipped back and forth between the protagonist’s and antagonist’s viewpoints. This made for a very eclectic story centered around two opposing forces.

The combination of suspenseful plotline and straightforward writing was very appealing for me as the reader, however, I also felt that its allure and simplicity would be an equally good fit for teens. I typically dedicate roughly an hour before bed for reading, yet with Deep Shadow I somehow found myself sucked into the story into the wee hours of the morning. Because of this, I destroyed the book in just shy of a week.

While the book had enough description to let your imagination take over, I could appreciate the fact that Deep Shadow didn’t use excessive wording to outline characters, places and events. I find I sometimes get lost in the chunky details of some books. Limiting the details to important and enriching ones, made for a nice flow in this rapidly evolving thriller. It also left breathing room for the story to progress at such a fast tempo without being overwhelming.

Personally, I felt an instant connection to the two main characters, particularly Emily Durand. I could relate so much to her character being a female scuba diver and underwater photographer. It was also a funny coincidence that she and I both happen to love the colour lime green.

Another thought I had almost immediately after finishing the book was – with the recent flurry of novels being used in TV and film, I would love to see this book (and likely the entire series) adapted for the screen. Deep Shadow was well written and so interesting, it would make for an intense edge-of-your-seat thriller, or at least I truly think so.

For any scuba divers in search of a good read on their surface interval, I would highly recommend Nick Sullivan’s Deep Series. If the first book is any indication of what’s to come I can only hope that I don’t finish reading the current four book-series before summer. But I can’t make any promises. As much as I want to prolong and savour this Caribbean action-packed novel, some books are too good to put down!
