Harlan Coben's Shelter

It tells the story of high school junior Mickey Bolitar (Michael) as he navigates his new life with a mom in rehab, a dead father, an annoying aunt and a new school in New Jersey with a camel as its mascot. When a creepy old lady who may or may not be a ghost tells Mickey that his father isn't dead, Mickey is sure he's losing his mind on top of everything.
