Can the future be changed by a trip to the past? Yes, theoretically. But when you are a lingerer – one who has died but remains on earth – it can be more than a theory, thanks to the special powers the dead possess. Sarabeth Morgan already knew about her own invisibility and the way that whatever she held became invisible too. She knew about a lingerer’s ability to fly and walk through walls, doors, and glass as well. But it takes Laura Peterson, nine years a lingerer, to clue her in to one very special power the dead a one-time chance to travel back in time to change something’s outcome—except the one thing a lingerer can't do is prevent their own death. Sarabeth, however, can see a loophole for that exception, at least as far as Laura is concerned. Laura had died of a drug overdose. If they were to go back in time, they can’t stop Laura from taking that final handful of pills, but what if they stopped her before she even began to do drugs? It could mean she would still die at the age she did the first time, but this time her death wouldn’t be a suicide. This was important to Sarabeth because, while dead herself, she was in love with Simon, Laura’s living brother, whose emotional life had been damaged by the death of his sister. Sarabeth wants to help Laura fix her life, although she can’t help but think Laura’s tale of time travel is a scam concocted by her and Jude Scariotti – who, like Simon, can see and communicate with the dead – in order to get Sarabeth’s assistance in another of Jude’s nefarious money-making schemes. Reluctantly, Sarabeth agrees to time travel with Laura for the sake of healing Simon’s damaged soul, knowing any misstep could ruin what time Sarabeth and Simon hope to have together. But time traveling as a lingerer was nothing like it was portrayed in movies and books… Transformation is Book 3 in The Ghost Girl Trilogy , and begins about six months after Ghostly Skills , Book 2, ends.
