From the author of Hemlock Island—the second novel in the #1 New York Times bestselling Otherworld series.

Elena Michaels is back—and she has company. When a young witch tells Elena that a group of humans are kidnapping supernaturals, Elena ignores the warning. After all, everyone knows there’s no such thing as witches. As for the thought of other ‘supernaturals’, well, she’d just rather not dwell on the possibility. Soon, however, she’s confronted with the truth about her world, when she’s kidnapped and thrown into a cell-block with witches, sorcerers, half-demons and other werewolves. As Elena soon discovers, dealing with her fellow captives is the least of her worries. In this prison, the real monsters carry the keys.
Lending a mission of vampires, demons, shamans, and witches, Elena is lured into the net of ruthless Internet billionaire Tyrone Winsloe, who is well on his way to amassing a private collection of supernaturals. He plans to harness their powers for himself—even if it means killing them.
For Elena, kidnapped and imprisoned deep underground, unable to tell her friends from her enemies, choosing the right allies is a matter of life and death.
