• In the Devil's cage
• Her memory forgotten
• Stolen from the world

The big mansion remains deep among the woods, unaffected by time, hidden in mystery, and dominated by one unyielding force: Mother.
Seraphine has lived under Mother's harsh authority for as long as she can remember, subject to rigid regulations meant to protect her from the horrors of the outside world. The house is all she has ever known, a shelter and a jail rolled into one. But as Seraphine gets older, she starts to hear things-whispers in the walls, the echo of invisible footsteps, and a voice in the darkness that is not Mother's. Then she sees it. A single crimson thread-thin as spider silk, throbbing as if alive, extending through the house and connecting her to something unseen. Something forceful. Something is hungry. Mother has spent years concealing the truth, but now the thread is unraveling, revealing the carefully woven falsehoods that have formed Seraphine's whole life. What's behind the closed doors? What happens at the conclusion of the thread? Why does she feel that the home is watching her? Seraphine's about to find out. And once she does, there will be no going back. The Sinister Thread is a haunting psychological horror tale filled with dark family secrets, spooky atmospheres, and a slow-burning mystery. It's about control, power, and the dreadful cost of the truth. Some ties are not intended to be broken.
