Aubrey Harrington just wants to get the community service hours she needs to graduate from high school. She never thought that taking the volunteer tour guide job at the local mansion would change her life forever. When she falls - or is pushed - down a flight of stairs, Maeve Somerton gives her a hand up, but the help comes with a price. Maeve thinks she was murdered, and now Aubrey must help her. Spiraling back in time, Aubrey feigns being Maeve's school chum to try to solve a mystery among strangers. Meanwhile, Aubrey also lays comatose in a hospital, and as her condition worsens, her family and friends wonder if she will ever come back to them. Caught in a twist of time and existence, Aubrey finds herself more ghost than alive in a world in which she was never meant to be. Will Aubrey be able to solve the mystery of Maeve's death? And even if she does, will she be able to find her way back home?
