Every fifty years, a cult claims twelve men to murder in a small Texas town. Can one girl end the cycle of violence--and save the boy who broke her heart? Eighteen-year-old Natalie Colter is sure that the rumors about her great-great-grandmother's cult of wronged women are just gossip, but that doesn't stop the true-crime writers and dark tourism bloggers from capitalizing on the town's reputation. It's an urban legend that's hard to ignore, and it gets harder when Nat learns that the sisterhood is real. And magical. And they want her to join. The more Nat learns of the Wardens' supernatural history, the more she wonders about the real culprits behind the town's ritualistic murders. Are the Wardens protecting San Solano from even darker forces? There are shadows in the woods, bones on the outskirts of town, and questions Nat needs answered. But everything becomes more urgent when people start getting "marked" as new victims--including Levi Langford, the boy whose kiss haunted Nat for a year. With Levi in danger, doing nothing would be harder than fighting back. Nat knows that no one is safe. Can she and the sisterhood stop the true evil from claiming their town?
