Jess Creary is stuck on an island with memories of her deceased sister. The only highlights are surfing and flirting with Matthew. When Jess is out surfing one day, she catches a wave that does the impossible and transforms her into a mermaid. As a mermaid, Jess has confidence and power. But as she gets closer to Matthew while on land, the line between her human and mermaid self starts getting blurrier, and not all in good ways as her rage for justice for her sister grows stronger. With a deadline looming for her to choose between the ocean and her humanity, there's no guessing which way the tide will turn.

Compared to witch or vampire stories, mermaid stories are often in short supply, especially ones that focus on myth and folklore. THE MERMAID'S SECRET is the perfect addition to shrinking the gap, weaving an entertaining and surprisingly touching tale of Jess and her quest for happiness. When the story begins, Jess isn't in a good place, as most twenty-three year olds can relate, and she's searching. Becoming a mermaid gives her something she hasn't found in her life on land, but it isn't a life without its own consequences. Jess's character development is fantastic, raising important questions about what it means to be human and what it takes to face your own circumstances.

While some parts of the story are a little slow, the plot is overall engaging and enjoyable. Once the deadline for Jess's choice is set, the pace steadily builds quicker and quicker. The romance with Matthew is a slow burn that eventually flares fast. Jess's best friend and roommate is a stereotypical, bubbly sidekick, but Jess's relationship with her father really shines.

With a wonderful ending, THE MERMAID'S SECRET by Katie Schickel is a moving exploration of the ocean, its secrets, and the nature of humans.
