For readers of C.N. Crawford, Laura Thalassa, and Jennifer L. Armentrout.
Interior design student Grace and twelve other humans are forcibly recruited to participate in order a contest, redecorating various rooms in Hell--which haven't been redone since ancient or medieval times. The winner gets a lucrative contract, a few extra decades of youth, and one soul reclaimed from The Pit. With sexy demons Razenath and Apollyon distracting Grace from her goals, can she avoid being eliminated after each round?
