Deep

"High Adventure Under Pressure! Nobody does underwater action like Nick Sullivan." -Cap Daniels, best-selling author of the Chase Fulton Novels.

"I thoroughly enjoy Nick's Deep Series, not just as a diver, but as an admirer of great adventure fiction. His characters are lovable, and just as importantly, believable. His storylines keep you turning pages, and the settings are written so knowledgeably that you feel you are on the island he's describing. Five-star Caribbean Suspense." Nicholas Harvey, best-selling author of the A.J. Bailey Adventure Series.

"Realistic And Suspenseful. 5 out of 5 stars! Sullivan is able to bring an insane amount of realism to his books that make them jump off the page. The emotional attachment I have to these characters keeps growing with each book." -Brian's Book Blog, May 12, 2020.

"This book is my new personal favorite in his Deep Series. Just when you think the story is about to wind down, Sullivan keeps throwing in head fakes and ramping up the action. Deep Roots is one of those books that will have you reading until dawn because you just can't help yourself." Don Rich, author of the Coastal Adventure Series.

"If you are one who adores well-written and expertly researched action adventures which can stand alongside the excitement and thrills of an Indiana Jones movie, you will want to have a listen to this new audiobook. As I have said in my previous reviews of Mr. Sullivan's works, I find that he provides a level of edutainment (education and entertainment) not often delivered from other authors I have listened to." -Quella Reviews, April 30, 2020

"Deep Roots is another great adventure thriller! This series just gets better and better. I really love Emily and Boone, our heroes. Their chemistry is spot on. I love their joking around, flirtatious behavior, and ability to take on bad guys. Note: Even though this is Book 3 in the series, it works as a stand alone novel." - Dab of Darkness Blog
