When librarians finally granted Kelley Armstrong an adult card, she made straight for the epic fantasy and horror shelves. She spent the rest of her childhood and teen years happily roaming fantastical and terrible worlds, and vowed that someday she'd write a story combining swords, sorcery, and the ravenous undead. That story began with the New York Times bestselling Sea of Shadows and continues with Empire of Night.

Armstrong's first works for teens were the New York Times bestselling Darkest Powers and Darkness Rising trilogies. She lives in rural Ontario with her husband, three children, and far too many pets.

If you had met me a few weeks ago, you probably would have described me as an average teenage girl?someone normal. Now my life has changed forever and I'm as far away from normal as it gets. A living science experiment?not only can I see ghosts, but I was genetically altered by a sinister organization called the Edison Group. What does that mean? For starters, I'm a teenage necromancer whose powers are out of control; I raise the dead without even trying. Trust me, that is not a power you want to have. Ever.

Now I'm running for my life with three of my supernatural friends?a charming sorcerer, a cynical werewolf, and a disgruntled witch?and we have to find someone who can help us before the Edison Group finds us first. Or die trying.
