Visit the shadowy places where monsters and demons roam in this collection by the New York Times-bestselling author of the Nightside and Secret Histories series. Welcome to the worlds of Simon R. Green. In this wide-ranging collection, the bestselling urban fantasist opens doors into hidden places: strange realms bordering our own mundane existence and prowled by creatures of fancy and nightmare. Here are the strange, frequently deadly–and sometimes even dead–things that lurk in garbage-strewn city alleyways and grimy subway stations after midnight, visible only to the most perceptive human or inhuman eye.

In these tales, Green revisits the ingenious worlds within worlds that he created for his wildly popular novels. Take a stroll on the Nightside with a jaded street wizard, an underpaid government functionary responsible for keeping demons, vamps, and aliens in line. Enter the hidden recesses of Drood Hall, where the aging family member who creates powerful weapons that protect humankind recalls his long and bloody career. Join a squad of no-longer-human soldiers dispatched to combat the all-consuming jungle on a distant planet. Visit a house at the intersection of two realities that serves as a sanctuary from the evil of all worlds. Confront the unstoppable zombie army of General Kurtz in a brilliant homage to Apocalypse Now. And whatever you do, never forget that there are monsters out there. Really.

Here are seventeen tales–each accompanied by an afterword by the author–of magic, sorcery, and the supernatural by a master of all that is dark.
