Jess Creary tragically loses her older sister, Kay, in a boating accident. It's suspected that Kay's boyfriend, Tripp Sinclair, may have had something to do with the death. Not long after, her mother disappears. Now two years have passed and Jess and her father are still trying to find their footing in life again. Jess has been distracting herself with surfing, working as galley staff on charter fishing boats, and quietly crushing on young, hot Captain Matthew.
On her 23rd birthday, Jess's father gifts her a necklace charm that she later discovers helps her morph into a mermaid with superhuman strength. While unsure of herself on land, in the sea Jess becomes a strong predator to be feared and respected. For the time being, Jess has the ability to move between both worlds, but she's soon informed that she'll have to choose one world or the other within the next 30 days.
Though the characters are all supposed to be in their 20s or older, this read more like a YA novel. Much of the plot emphasis seemed to be more centered around navigating difficulties within family or friendships or summer jobs / romances rather than the paranormal aspect. I would've liked to have seen the story go deeper with the Native American mythology... until you get closer to the end of the book, the references are kinda minimal. Even the passages discussing Jess's experiences as a mermaid are brief.
A good light summer read, entertaining for what it is, I was just hoping for a little more depth and atmosphere overall.
