Meg Cabot - Love you to Death (Mediator 1) (2000)

Susannah Simon is a mediator - she resolves issues for the dead and sends them on their way, sometimes a little forcefully with a bit of chicken's blood, some vanilla scented candles and a small exorcism.  No big!

All this was fine in New York, who'll notice the crazy amongst rushing millions? But, Suze's mother re-married and moved to California, the land of sun, surf and homicidal ghosts. Not to mention her lush new bedroom is already occupied - by a dead-cute boy.

Between a new high school, family and the undead Suze might just be in over her head.

This was an AWESOME book! I love Cabot's take on 'I see dead people'.  It's nice to see (mostly) ordinary ghosts who are just like when they were alive and generally need one thing resolved so they can move on. It's teenage fiction, so I didn't expect horror anyways, but Cabot brings a cheerfulness to the story that really draws you in and makes you happy.
