Kat Summers isn't exactly normal. Stranded as a child and recruited by the Hunters at eight years old, she's been killing Lycans since she can remember. Eleven years later, she's one of the most experienced Hunters to have ever graduated at the facility and is tasked with her most testing mission yet: execute the leader of the Nightshade Lycans. Kat is thrilled with her new task, until her mission goes horribly wrong. A misfired arrow, a mysterious Lycan boy and one bite are all it takes to throw her world into chaos. And as it turns out, it's hard to hunt Lycans when you've been Turned into one.
