Teenage Penryn is living in Silicon Valley with her wheelchair-bound young sister Paige and her paranoid schizophrenic mother when the angel Gabriel comes down from heaven and is killed by humans, kickstarting a global reign of angelic terror. Penryn is tough and brave and loyal and a wonderful heroine, and she is joined in her fight to save her family by the wingless angel Raffe, a brooding enigma of a creature (though I feel he should be allowed some slack as he did have his wings cut off). I wish Ee hadn't skirted around the issues of religion that make angel literature so much more compelling than, say, vampire literature, because an entire book about a human woman and an angel man running from place to place is never going to be as engrossing as a story that confronts the fears and needs of humanity.
