Fathomless by Jackson Pearce

Source: Publisher
Celia Reynolds is the youngest in a set of triplets and the one with the least valuable power. Anne can see the future, and Jane can see the present, but all Celia can see is the past. And the past seems so insignificant -- until Celia meets Lo.
Lo doesn't know who she is. Or who she was. Once a human, she is now almost entirely a creature of the sea -- a nymph, an ocean girl, a mermaid -- all terms too pretty for the soulless monster she knows she's becoming. Lo clings to shreds of her former self, fighting to remember her past, even as she's tempted to embrace her dark immortality.
When a handsome boy named Jude falls off a pier and into the ocean, Celia and Lo work together to rescue him from the waves. The two form a friendship, but soon they find themselves competing for Jude's affection. Lo wants more than that, though. According to the ocean girls, there's only one way for Lo to earn back her humanity. She must persuade a mortal to love her . . . and steal his soul.
I love this series. Pearce creates such dark,  but complicated retellings of fairy tales and I just need more. Celia was such a sweet character and I understood her character a lot. Her sisters were harder to understand, but I still found them to be entertaining. I liked how they blended together, because sisters tend to be very similar yet slightly distinct. I like Lo too. The romance in the story was beautiful and I liked that Pearce made the plot surprising and enjoyable. The plot drew me in and enchanted me into wanting to read more.  I find her originality to be amazing and the story was well crafted as a result. Pearce crafts another beautiful retelling of a fairy tale and I can't wait to read more books along this way. If you have enjoyed her other books, you must read this one now. It is very similar to Sisters Red and Sweetly and dives deeper into the story.
