The Proof That Ghosts Exist

In The Proof That Ghosts Exist — the first installment in The Ghosthunterstrilogy — Molly and Adam managed to save their father from a family curse, and near-certain death on the day before his 35th birthday. Or did they? 

An unfortunate “error” on their dad’s birth certificate means that he’s still at risk, and it’s up to Molly and Adam — and their ghostly grandfather — to keep him safe. But how are they going to manage that when he’s off to Palm Springs, California for a film festival?
