While searching for her missing bayou-pirate cousin, Kallie Riviere, a fiery Cajun hoodoo apprentice with a talent for trouble, finds out the hard way that someone's undoing powerful gris gris down in the bayou and changing the very nature of magic. Suddenly working magic is like rolling a handful of dice - random and definitely not what you planned. Now the wards woven by conjurers to protect New Orleans and the Gulf coast are in danger of unraveling, leaving the city and the coastline vulnerable just as the deadliest storm-- unnatural storm-- in a century is born and aims for New Orleans's heart. As Kallie races to uncover the random magic's source and restore the wards, she learns a dark and unsettling truth: she might be the source. Then Kallie steps right into the most dangerous trap of all, a trap set just for her in the form of a tall, dark, and grumpy loup garoudesigned to steal her heart.
