From the author: "This is a story where the Meet Cute happens on an autopsy table, but I promise you it isn’t about vampires or zombies or anything supernatural. It’s actually about dealing with personal tragedy and life-long mental illness! With sexy results!"
From pinboard.in: "the one about the morgue attendant and the not-corpse, with buckets of fabulous characterization"
