Newly single college student Shelley Igor is looking forward to a chill weekend in the mountains with her two favorite friends with benefits: twisted genius Dr. Isadora Von Frankenstein, and Frankenstein's terrifying but lovable monster, The Monster. It'll be good to catch up, hang out, and have plenty of casual sex with no emotional complications. She's got some fun new bondage ideas to try out, and maybe she'll break out that schoolgirl costume the doc likes so much.
It should all be a nice change of pace from serious stuff like love. But when uncanny events at Frankenstein's secret lair spiral out of control, Igor's in for the craziest night of her life. She'll be so busy dealing with ghosts, evil twins, missing underwear, Frankenstein's dead fiancée, and who knows what else, she'll barely have any time to make new friends. On top of everything, she might end up having to confront her own inconvenient feelings for Frankenstein and The Monster, with the most inconvenient possible timing.
This steamy take on Jekyll & Hyde is the second installment in the Isadora Frankenstein series, and it can be read as a standalone.
