Charlotte McConnor has all the luck of the Irish... until she doesn't. When she agrees to marry Colin, her boyfriend of several months, things go downhill fast. The second the engagement ring slips on her finger, things get strange—and hot. As in, he burns her hometown to the ground every night in a sick game of cat and mouse.

Unbeknownst to Charlotte, she's just met her sin-eater—the man cursed by her family to carry her sins to Hell and keep her cup of luck overflowing. Now he's out for revenge. Unless, of course, they can figure out a way to break the centuries-old curse that has enslaved them both.
