There's something achingly familiar about Daniel Grigori. Mysterious and aloof, he captures Luce Price's attention from the moment she sees him on her first day at the Sword & Cross boarding school in sultry Savannah, Georgia. He's the one bright spot in a place where cell phones are forbidden, the other students are all screw-ups, and security cameras watch every move.

One minute, sixteen-year-old Zoey Redbird is a normal teenager dealing with everyday high school stress: her cute boyfriend Heath, the school's star quarterback who suddenly seems more interested in partying than playing ball; her nosy frenemy Kayla, who's way too concerned with how things are going with Heath; her uber-tough geometry test tomorrow. The next, she's Marked as a fledgling vampyre, forcing her to leave her ordinary life behind and join the House of Night, a boarding school where she will train to become an adult vampyre.

Hell on Earth. That’s what it’s like for Luce to be apart from her fallen angel boyfriend, Daniel. It took them an eternity to find one another, but now he has told her he must go away. Just long enough to hunt down the Outcasts - immortals who want to kill Luce. Daniel hides Luce at Shoreline, a school on the rocky California coast with unusually gifted students: Nephilim, the offspring of fallen angels and humans.

When fifteen-year-old Clary Fray heads out to the Pandemonium Club in New York City, she hardly expects to witness a murder - much less a murder committed by three teenagers covered with strange tattoos and brandishing bizarre weapons. Then the body disappears into thin air. It's hard to call the police when the murderers are invisible to everyone else and when there is nothing - not even a smear of blood - to show that a boy has died. Or was he a boy?

Luce would die for Daniel. And she has. Over and over again. Throughout time, Luce and Daniel have found each other, only to be painfully torn apart: Luce dead, Daniel left broken and alone. But perhaps it doesn’t need to be that way...Luce is certain that something - or someone - in a past life can help her in her present one. So she begins the most important journey of this lifetime...going back eternities to witness firsthand her romances with Daniel...and finally unlock the key to making their love last.
