A twelve-year-old boy with a passion for ghosts thinks his dreams have been answered when his father buys a mansion rumored to be haunted. But Grayson soon finds himself terrified by a creepy chair that keeps reappearing, even after he burns it in the fireplace. He also sees apparitions of a hanged woman, and hears poltergeists that shake the furniture. He realizes the real paranormal is much scarier than anything in his imagination and asks his father to hire a ghost hunter. He is pleasantly surprised, as well as smitten, when a sassy, hip teen girl named “Nena” shows up. “Ghostologists don’t hunt ghosts,” she explains. “We study them.” Together they explore the horrific old house from top to bottom, from his father’s chemistry lab in the basement to the upstairs ballroom, library and observatory. But in seeking the portal to other worlds they learn valuable lessons about this one, about love and loss, childhood and family, guilt and forgiveness, and discover a special bond that will keep them solving mysteries for a long time to come.
