Shadowglass

Welcome to secret world hidden behind shadowy fairy glamour, where thieving spriggans rob you blind, beautiful banshees mesmerize you with their song, big green trolls kick heads at nightclubs and vampire Mafiosi rule the streets. This is the world of Erica Hayes' Shadowfae Chronicles. Here, in Shadowglass, a seductive magic mirror lies hidden deep in a demon's lair, with a simple warning: don't stare at the glass...
Ice is a light-fingered fairy who can't resist a look at the powerful mirror. She and her fairy friends run confidence games, pretending to be fortunetellers and bedazzling customers with their glamour. But, Ice longs for more-she wants a real life, a respectable job and something to strive for. The mirror offers her a chance to achieve everything she's ever dreamed of. But, when she pilfers it, she discovers that its power comes with a price: the mirror is a gateway to obsession and madness... and it will take every trick in her arsenal just to survive.
