YA fantasy author Catherine Webb (The Obsidian Dagger
) makes an ambitious leap to adult urban fantasy under the Griffin pseudonym. Matthew Swift, a young London sorcerer, was brutally killed thanks to the machinations of Robert James Bakker, a superpowerful mage who also targeted several of Matthew's colleagues. Two years later, Matthew revives as a “we,” sharing his body with an “electric angel.” While seeking answers, Matthew meets magician Dudley Sinclair, who wants to kill Bakker and crush his group of evil dark arts practitioners—including Matthew's former apprentice, who has become Bakker's lover. Griffin's lush prose and chatty dialogue, modeled after the best work of other modern British fantasy writers, create a wonderful ambience but often diffuse the tension, leaving readers to make their own way through the uncomplicated plot.
