I loved this book, you can find my review for it here.
Fifteen-year-old Piper Crenshaw knows her house is strange. It’s never needed repairs since it was built in the 1800s, and the lights flicker in response to things she says. As if those things aren’t creepy enough, it’s also the place where her mother committed murder.
To prove she’s not afraid of where she lives, Piper opens a forbidden door, which hides a staircase that leads to the ceiling. That’s when the flashbacks of the original residents from 1875 start, including a love affair between two young servants. Each vision pulls Piper deeper into not only their story, but also her house. Piper confides in her best friend, Todd, whom she's gradually falling for, but even he doesn't believe her. At least, not until her house gets axed during a prank, and the act injures Piper instead, cutting a gash the size of Texas into her stomach.
Piper realizes her house isn’t haunted—it’s alive. To sever her link to it, she must unravel the clues in the flashbacks and uncover the truth about her mother’s crime, before she becomes part of her house for good.
