In a storm, you never know which way is home. Tish Yearly is about to open a wedding venue on Orcas Island, in the San Juan Islands of Washington State. All she wants is to sail through her first wedding, figure out why her best friend isn’t talking to her, and tell her grandfather she’s dating someone he doesn’t approve of. But before she can get to any of that, Tish’s favorite employee turns up dead—apparently drowned in four inches of water. Now Tish, and her grandfather, former CIA agent and current curmudgeon and licensed P.I. Tobias Yearly, are wading through the suspects including a meth-cooking uncle, a brother with anger-management issues, and the mysterious island drug kingpin, who may or may not be going straight. Tish is attempting to navigate this unfamiliar sea, but she may not be able to weather the storms to find her way home.
