All T wants is a break from her day job. After months of fighting angry demons and keeping humanity oblivious to the Underworld, she needs some time off. Her solution is brilliant: A girls’ day out, full of shopping, massages, and mani-pedis. Luckily, she has a friend to bring along—her business partner, J. Unluckily, J wants nothing to do with T’s plan. T manages to drag J along, promising a day full of pampering and relaxation. But the Underworld has different plans. When T and J are attacked by a pack of demons, their girls’ day is ruined and replaced by something much more sinister: A life-or-death investigation into the person—or demon—who wants them dead.
