When Owen Blackwood is called across time to a seemingly normal home to destroy a haunted painting, it didn't feel like anything out of the ordinary to this agent of Wolvenheart. Upon arrival, however, Owen finds himself trapped in the very painting he was called to destroy. With only a one hour window of time in which to operate, will Owen be able to save the family from certain death and destroy the painting? Or will he get lost in time and become a cross-dimensional walking ghost? Hour of the Wolf is the second thrilling title in Underworld, an all-new universe created by Mark London which also includes Revolution 9 (launching in September) and Exit City (launching in November). Each miniseries set within can be savored as a standalone serial, while serving as a stepping stone towards ENDLESS NIGHT, the must-read crossover guaranteed to blow your mind in 2025!
