Darkness Unbound

Keri Arthur's new Dark Angels series launch expands the world of her Riley Jenson Guardian series, a generation later. Australian restaurateur Risa Jones is half werewolf, half Aedh (a race that can dissolve into mist), and daughter of earlier protagonist Dia Jones. While helping one of her clairvoyant mother's clients, Risa discovers a soul stealer. Later events reveal a calamitous plot that may involve Risa's mysterious father and the keys to hell's gates. As Risa tries to stop the soul stealer and understand the significance of the keys, she gets a little help from her friends: a hacker, an inscrutable reaper with his own game plan, and an Aedh she meets and beds along the way. A well-foreshadowed but still shocking d%C3%A9nouement may bother some readers, but as always, Arthur uses the sacrifice to power a thrilling ride. (Oct.)
