Two young women race to turn the tide in a Florida on the brink of civil war... Everyone knows that Jonnie trains and races the limerunners, the deadly water horses that live in the swamps and streams around the town of Sawgrass, and that she's got a way with them that none of the local men can match. And everyone suspects that while Bess works at her family's inn, The Nag's Head, she sews her little nothings, magic in every stitch, to protect her beloved Jonnie and their family. What they don't know is that Jonnie runs messages, stitched in code by Bess, for the Union Army. But now the Confederate forces have taken the nearby fort and they want to use Jonnie's limerunners and Jonnie herself as weapons against the Union. And all of Bess's magic won't be enough to save them when they're caught in a web of betrayal in a Florida being torn apart by burgeoning civil war. Only Ada Nuit, the Maroon's ghost queen, knows what lies in store for them and she's not telling...
