The Sandman Presents: Petrefax Series by Mike Carey

When the beautiful, stubborn Calcinia Smith tries to escape a forced marriage by using gypsy magic, she becomes trapped in a physical limbo—her soul intact, but her body dead and deteriorating fast. Hired to embalm her, Petrefax is now the only one who knows her secret—and the only one who can keep her "alive."

He's just narrowly escaped hanging for feigning a funeral, but now Petrefax finds himself in an even more precarious situation. Caught in a battle of magical intrigue, how will our young undertaker escape unscathed?

Separated from the beautiful Calcinia by the magical wiles of her jealous would-be groom Lord Bulgus, Petrefax continues alone on the quest to find a wizard who can literally save Calcinia's soul.
