Best Friends Forever — Patti Larsen

A tragic accident strips sixteen-year-old Emily Underman of her three best friends. Depression consumes her as life becomes the endless gray place of feeling nothing. Until her little brother goes missing, jerking her out of her emotional coma. That's when her friends appear. Haunting her, driving her to madness. Trying to tell her something. Making her question the motives of the lead detective on her brother's case. Doubt the nice man next door. And making it hard for her to resist the only person who understands her -- the detective's son, Todd. Guilt forces her to trust the spirits of her ghostly friends who lead her closer and closer to the kidnapper -- and redemption.
