Gavin Booker, a school librarian, leads an orderly, normal life. Work, jogging, friends from work, his son every other weekend. Gavin is also a secret. He is a hybrid, or part-fairy. And in the Columbian Empire, hybrids are under an automatic death sentence.
In this alternate version of the USA, magic is illegal. So is loving another man. Fairies are locked away in ghettoes, and magical beasts, such as gryphons, unicorns, and pegasi, are kept in zoos. The others, tree and water spirits, talking beasts, fauns, and the rest, are in hiding.
This is the world in which Gavin grew up. He survived, thanks to his mother. He can never forget he is different: ministers preach against people like him constantly. Hating the other is a part of every school's curriculum.
But things are changing fast, and seemingly for the worst. Earthquakes, volcanoes, killer storms are frequent occurrences. The medicine Gavin takes to suppress his body's glow isn't working. The spells cast by his doctor, a witch, are losing their power. If anyone finds out what Gavin is, he is dead.
The Empire always goes after its marginalized people. Can Gavin survive the coming catastrophe? Will he ever recover from losing the boys he loved earlier in life? Can he find the fairy man who has haunted his dreams before it is too late?
