Unknown is the second book in author Rachel Caine’s Outcast series which is a spin-off of her Weather Warden series. The book starts right where Undone left off, with the former Djinn Cassiel working with Weather Warden Luis Rocha to track down the rogue Djinn Pearl who is behind all the kidnapped Warden children. Pearl captured Luis’s niece Ibby and, with Cassiel’s help, must try and rescue these kids before the insane Djinn can use them in her diabolical plans.

Cassiel is learning more and more how to be human, while trying to decide whether to follow through with what the Djinn want of her to regain her full powers back. (more…)
