Tamsyn Hallert, an artist, exists in a vicious circle of addiction and recovery, fueled by her husband Sean's long-time secret affair. The affair ended in his lover's bizarre suicide, but not before she left a surprise on Tam and Sean's doorstep—Kevin, the son Sean never knew he had. Sean moves them to the country, to his familial home near the crumbling Wraithborne Estate, the massive old house with a terrible mythos. The twisted attempt to save their marriage only makes matters worse as Sean's obsession with his dead lover deepens, and Tam's grip on reality grows more tenuous. A horrific plot to summon the dark spirits that possess the Estate comes to light, with Tam, Sean, and Kevin in the center of it all. Will Tam be able to save her family, or will the lure of the spirits' promises be too strong to resist?
