Breathless

by Brian Roberts

Aiko Uchiumi always lived between two the academic pursuit of marine biology and the ancestral calling of the sea. As a college student, she dreams of researching the coral reefs she loves and following in her grandmother’s footsteps as a legendary Ama freediver. But her quiet life shatters when her best friend gives her what seems like an innocent gift, but hidden within is a cryptographic key worth billions.

What's the catch? This fortune is locked inside a safe entombed within a rusting shipwreck, resting in a perilous grave at the bottom of the sea.

Now, ruthless treasure hunters, hackers, and mercenaries are all converging on Aiko, determined to take the code from her at any cost. As Aiko races to reach the wreck before they do, she must confront a difficult Who can she trust? And as she plunges deeper into a world of secrets and betrayal, where the ocean itself is as dangerous as those who would kill for its hidden fortunes, Aiko discovers that some treasures are worth more than money, and some secrets are better left at the bottom of the ocean.

An adventure so deep it will leave you Breathless!

Wow, was this exciting. I haven't read an underwater adventure this good in quite some time. The descriptions of Okinawa and Zamami Island were so detailed that I felt like I was there while reading. The underwater chapters felt so real, I found myself holding my breath. And thanks to the author, I stayed up until two am on a work night so I could finish reading! The book is wonderfully formatted and is very easy on the eyes and easy to read.

I can't wait until the sequel comes out.

This book was like a classic Clive Cussler adventure. In this story a young woman named Aiko has to dive into a shipwreck to find a safe. The underwater scenes were so descriptive, I felt like I was in the story along side of Aiko. This is a really good story.
