This is the sixth volume in the Women of the Otherworld series, and the third to feature the werewolf Elena. Elena is pregnant, and given that the Pack has never thought it possible for two werewolves to reproduce, they\u0012re all guarding Elena very carefully, and making her very, very restless. So she jumps at the chance to do a deal with Xavier, the untrustworthy half-demon. In exchange for locating the rogue werewolf who murdered three women, Elena agrees to retrieve a stolen letter supposedly written by Jack the Ripper. Unfortunately, the letter contains a magical gateway to the past, which, once opened, disgorges two zombies and a murderer into the present day.
