The Lost Weekend. Dead Mall, #6

Cari Hembert is living the dream. Literally. Having succumbed to a routine bout of hypersomnia, Cari finds herself older and settled in a beautiful house by the sea that she shares with Rex, her live-in boyfriend. So this is what it feels like to have it all. But Cari soon discovers that, even in the sunniest dreams, the dark secrets of the past will always find you... Meanwhile, a new tenant is coming to Edengsate: MondoMart, the high-end big box store that is all but guarenteed to reinvigorate the mall.
There's just one problem: it's going to be open 24 hours a day. To save the town of Halcyon (and possibly the world) from becoming an all-night buffet, the crew of Virgil Security and Maintenance must stop the underworld invaders once and for all. And they only have forty-eight hours to do it. The Lost Weekend is the sixth book in the Dead Mall novella series, where saving the world from the forces of evil is all in a night's work.
