One

When a shapeshifter, a werewolf, a vampire and a warlock get assigned to a rescue mission, they hardly expect to get along, let alone fall in love while uncovering a deadly operation that could destroy the supernatural world. Catherine Williams is a prodigy shapeshifter with a penchant for adventure. A rescue mission however gives her more adventure than she'd bargained for as a series of gruesome murders threaten to tear apart the supernatural world. As different species begin to turn on each other, it's up to Catherine, Cassius, Desmond and Azriel to bring the supernatural world together before it's destroyed for good.

A polyamorous love story with a healthy dose of magic.
