Elspeth, The Living Dead Girl

If you're dead already, can you die again? Elspeth's been summoned from limbo. Her new assignment? Track down the culprit in the mysterious death of a student at Clearwell High. And incidentally, uncover the identity of the new drug dealer prowling the halls. Only one problem-the body she has to co-inhabit has a different agenda. Elizabeth just wants to be prom queen, marry Prince Charming, and graduate with perfect posture. Both girls, alive and dead, will have their separate worlds rocked before the killer is unveiled. Nothing is as it seems. No one can be trusted. Being dead has never been so dangerous.
