If you enjoyed Rick Riordan’s son-of-Poseidon type of mythology), you’ll enjoy this series. Some people possess “dark gifts” which are supernatural talents that make them slightly more than human. The main character, for instance, possesses an ability to use sonar. Technology is now capable of providing humans with a substance that when inhaled, allows a person to breathe underwater.
There’s sea monsters, mystery, kidnapping, and murder. There’s also a light teen love story accompanying this action/adventure story, but it’s definitely secondary to the storyline. When Ty and Gemma accidentally uncover an entire settlement that was trapped and sunk to the bottom of the ocean (a chilling scene involving frozen corpses found chained inside the homes of their sunken township), they find themselves part of a dangerous plot as they attempt to rescue Ty's kidnapped parents.
I jumped into this series with Rip Tide, but the book is fairly accessible for new readers. The plot is slightly complex, despite the length of these novels. The conspiracy aspect and the different types of people in this aquatic world require a slightly more advanced reader who can handle a multi-layered plot.
An interesting book to say the least, full of colourful characters and featuring the dark and deadly side of the ocean-- without frightening young readers. I loved the setting and the world that Kat Falls created. She is a skillful writer and I look forward to reading her latest book, Inhuman.
