Donna McCormick is a smart, pretty college student whose twenty-first birthday is a week away. Unfortunately, so is her murder - unless the mysterious man from the darkness can reach her first. Donna is pursued in her dreams by a man who claims to be her Eternal Partner. During her waking hours, she’s cornered by another who claims to be the same. There’s only one problem: neither is entirely honest. Or, for that matter, entirely human. Eight years earlier, Donna’s life was dealt a terrible blow with the untimely death of a little brother who was left in her care. Ever since, Donna has yearned to get a normal life back – and despite her best friend Mo’s efforts to the contrary, Donna has almost managed it…at least until the Underworld cracks wide open, scattering chaos and spilling out every shifty force under the moon. Most of them want Donna dead, but some will stop at nothing to keep her alive. Too bad she doesn’t know which is which. With death following Donna like a shadow, she turns to her best friend for help. But instead of help, Mo offers only more mystery. And she knows more about the Underworld than she's willing to admit.Now, Donna must choose: Cling to the mortal world where she feels safe, or embrace the Underworld where her dreams – and nightmares – come true.One thing’s for sure - doing either one might get her killed in both.
