A magical island. A mysterious relative. A family she didn't know existed.

Inheriting a house from a dead great-aunt she’s never met should've been Sara Rivers' first clue that things were about to get weird. The talking sea otter? That was clue number two.

Sara's plan was simple: stay the six months to get her inheritance, sell the house, and figure out what comes next. What she didn't plan on was discovering she's half witch, half undine, has magic she can't control, and has a family history she was never meant to know.

Then a suspicious journal entry makes her doubt everything she's been told. The locals are friendly, the town is charming, and absolutely no one wants to talk about how her great-aunt really died.

When another body turns up, Sara realizes the killer isn’t done.

Between mandatory magic lessons, the game shop she inherited, a runaway teen hiding out in her basement, and an infuriatingly attractive FBI agent who may (or may not) be on her side, Sara's getting closer to a truth someone killed to hide. And the killer is watching.

Welcome to Spelltide Bay, where the gossip travels faster than seagulls, sea otters have opinions, and secrets never stay buried for long.
