Cherish (a YA Ghost Mystery)

It's the sophomore Local History cemetery visit. Sure, it's almost Halloween, but Kayla has seen that ghost for years. She wants to make the ghost go away, but she shouldn't have touched her hand, because, That's When Everything Changed. Kayla finds herself in 1946 as someone else, someone whose name is on an elaborate tombstone. Is she Cherish, or is Cherish her? Is Cherish taking her place? Fact: Cherish is ruining her life in two centuries. If Kayla doesn't find her way home to her own time and her own body, she will die with Cherish in a few days. Question: Do cell phone texts span the centuries? And, if they do, will Kayla's friends believe her?
