Hallowing, The (Vintage Paperback) by Fran Pokras Yariv

It was a night for dying. Nothing human could have survived that flaming car crash. Sharon Jenner did.

She couldn't tell them why; she was in terror of the answer. Because Sharon Jenner, ideal wife, mother, working woman, could no longer understand anything...not the tumor that disappeared...not the rock that moved at her wish...not the midnight visitation in her garden...

What awesome power had been bestowed on Sharon? And was it a gift...or a curse?
