Marked

Marked is the first book in Kim Richardson's Soul Guardians series. Ordinary teenager Kara Nightingale is killed in a freak accident and wakes up in a strange otherworldly realm, where she is recruited as a rookie in the Guardian Angel Legion — a world where monkeys drive the elevators, oracles watch over giant crystal balls, and demons feed on the souls of mortals.

Kara's new life is upended when a mysterious Mark appears on her leg and the Legion accuses her of being a demon spy. As angels around her begin to die and her partner David pulls away, Kara must prove her innocence and uncover the truth behind the Mark before it costs her everything.

The novel blends humor with supernatural adventure and won a Readers' Favorite Award in 2011.
