The Rise of Amphitrite (A Trident Trilogy #1)

Amy—short for Amethyst—has had her life planned out for her since before she could excel at cello, fencing, and academics, attend Oxford early, and take over her father’s law firm after her 20th birthday. She’s never had much free time for friends, aside from Percy, the boy who washed up on the beach in front of her as a child and hasn’t been far from her thoughts since. Percy teaches her about mythology, and sometimes it feels like they’ve known each other much longer than a few years… When Amy chooses saving the oceans over the family business, moving halfway around the world for a marine biology research position, strange things start happening. The sea and its creatures seem to react to her presence, locals are calling her queen, and she’s feeling off, like part of her is missing. Her coworkers are great, but they seem to be taking all of this a bit too in stride. When the research ship is attacked by creatures that should definitely not exist at the same time Percy shows up for a visit, Amy has some serious questions. She’s soon confronted with the fact that she may not be in charge of her destiny after all, and more than her own happiness is riding on her choices.
