Fire in Frost (Crystal Frost Volume 1)

Details: 

Crystal Frost tells herself she isn't crazy, but sane people don't see ghosts. As her psychic abilities manifest, Crystal discovers there's a much bigger story behind her mother's Halloween-themed shop than she ever realized. Now blessed with the ability to see into the future, witness the past, and speak with the dead, Crystal must use these tools to save those who have come to her for help.

But that's not an easy task between learning how to use her abilities, trying to hide them, and uncovering the secrets her loved ones have been keeping from her. Add blackmail to the list of things Crystal never thought would happen to her, and you basically have her sophomore year covered. Will she learn to control her abilities in time, or will the whole school learn of her secret before she's ready to reveal it?
