Lake Superior is home to hundreds of shipwrecks . . . but only one mermaid. "H" doesn't know where she came from. She doesn't even know her full name. That hasn't stopped her from having a good time: she's spent the last few decades evading tourists, befriending local wildlife, and sharing spectral martinis with shipwrecked spirits. But there are whispers in the waters, rumors of a strange new threat killing whitefish by the hundreds. Out of the deep blue nowhere, H finds her North Shore paradise under attack. H must unravel her origins and harness long-dormant powers to lead Gitchi-Gami's residents (furred, finned, and ectoplasmic alike) in the fight to reclaim their waters. It will take unexpected allies, divine intervention, and pie . . . lots of pie.

Includes maps as well as numerous charming black-and-white illustrations by artist Jill Myer.
