Grounded

A middle grade novel about a 12-year-old girl dealing with loss, who uncovers a rather grisly scam involving a crematorium.
After her brother, sister, and father die in a plane crash, Daralynn Oakland receives 237 dolls from well-wishers, resulting in her nickname: Dolly. But dolls are little comfort to a twelve-year-old girl whose world is rocked by the dramatic changes in her life, including her angry, grieving mother's new job as a hairstylist at the local funeral home.
Dolly gets a job, too, where she accidentally invents a fashionable new haircut. But in Grounded by Kate Klise, her real work begins when a crematorium comes to town, and someone has to save a dying business, solve a burning mystery, and resuscitate the broken hearts in Digginsville, Missouri, population 402.
