Suze and Jessie's relationship is put to the test in Grave Doubts, the fifth book in Meg Cabot's The Mediator series.

Suze is in deep. She loves gorgeous, ghostly Jesse but fellow mediator, Paul Slater, is determined to win her heart. And evil Paul knows how to blast Jesse to the Great Beyond. For good.

Paul promises he won't do anything to Jesse, as long as Suze will go out with him. Suze doesn't want to lose Jesse forever, so she agrees. But now she's having grave doubts: can a girl really have a future with a guy who's already dead?

Other books in the series include Love You to Death, High Stakes, Mean Spirits, Young Blood and Heaven Sent.
