Girl vs Ghost

Isabel Lindley doesn't believe in magic, but her best friend is obsessed with witchcraft. Strictly as a favor, Isabel agrees to help with a spell and is shocked when the ghost of a teenage boy splat-lands in her bedroom. Her friend is thrilled-even though only Isabel can see or hear the ghost-but Isabel is horrified. She's the most ordinary sixteen-year-old girl on the planet. What is she supposed to do with a ghost who doesn't know his own name, how he died, or why the heck he's tied to Isabel with a psychic chain? Her only hope to take back her life is to help him solve the mystery of his demise so he can go to the Light. Or wherever. She's not particular, as long as the ghost is gone.
