Timeless - Laura Legend

Cassandra Jones is timesick. Her battle with the Lost left her physically shattered, and the personal losses she suffered there left her emotionally unstable.

As Cass battles for her life in a continual swirl of past, present, and possible futures, Richard York struggles to keep her safe and find a cure for the disease that is clearly killing her. He knows she cannot abandon Zach, but knowing that truth only strengthens his desires to heal her. When Maya agrees to help him, he's grateful. At first.

Cass has her own ideas about how to heal. And they don't involve Maya. Chased by a growing horde of vicious shadow demons able to attack her even as she sleeps, Cass fights her way through the mobs of renegade Lost vampires who want her blood. She's ready for them though: turns out a timesick seer can still kick ass.

A timesick seer is a recipe for disaster. Tick tock, Cassandra Jones. Time to run.
