Every other day, Kali D'Angelo is a normal sixteen-year-old girl. She goes to public high school. She argues with her father. She's human. And then every day in between... she's something else entirely.
Though she still looks like herself, every twenty-four hours predatory instincts take over and Kali becomes a feared demon-hunter with the undeniable urge to hunt, trap, and kill zombies, hellhounds, and other supernatural creatures. Kali has no idea why she is the way she is, but she gives in to instinct anyway. Even though the government considers it environmental terrorism.
When Kali notices a mark on the lower back of a popular girl at school, she knows instantly that the girl is marked for death by one of these creatures. Kali has twenty-four hours to save her, and unfortunately she'll have to do it as a human. With the help of a few new friends, Kali takes a risk that her human body might not survive... and learns the secrets of her mysterious condition in the process.
Barnes (the Raised by Wolves books) delivers a gory urban fantasy that balances confident world-building, action, and strong character development. The sharp-tongued 16-year-old narrator, Kali D Angelo, wields strange, superhuman powers, but only every other day, during which times she secretly goes out and slays various supernatural creatures. (In this world, such creatures were discovered by Charles Darwin and have long been known to human society.) On one of the days when she s merely human, Kali discovers that her uptight cheerleader classmate, Bethany, has the always-fatal mark of the chupacabra and contrives to transfer the mark to herself. The combination of Kali s powers and the supernatural creature is bad enough, but it s soon clear that there are rogue scientists and other dangers to both girls and a third classmate, the potentially psychic Skyler. The conspiracies and supernatural threats vie for time with lone-wolf Kali s attempts to deal with two potential friendships; all of the conflicts come to a head in an extended but gripping climax. Fans of adult-oriented urban fantasy should enjoy this as much as teens looking for a contemporary Buffy. Ages 12 up.
