The Binding: Chronicles of Azaria (Book One)

All seventeen year-old Eliza Bryant wants is to avoid a Binding-- the ancient spell that forces couples into a lifelong bond. It cursed her sister, and for the last two years it's tried to claim her, too. Her monthly hiding ritual worked brilliantly, until the night she ran into Ryan, a mysterious bounty-hunter. Now Bound to him, Eliza must spend every moment at his side, else she'll transform into an Unbound; a lifeless husk without mind or soul.

Unfortunately, Ryan's not looking to settle, and Eliza is dragged into his crazy life on the run. Still, she's not going to take this lying down. Between grappling with the false feelings conjured by the spell and fleeing an unseen enemy, she plans to find a way to break her Binding; a feat nobody's achieved in two thousand years. The key to her freedom lies closer than she thinks, and it's deeply connected to Ryan's past.
