The Spider Catcher (Redemption by A.L. Tyler Book 1)
Some family trees are pretty twisted and too thorny to touch.

Ember Gillespie was sent away from the island of Tulukaruk when she was only a child. Now returning as a teenager, she's finding that the life she idealized from afar is actually a living nightmare, complete with a deranged family that is trying to drive her away and a town full of creepy people.

Her only refuge from the constant strain comes from the subtle and mysterious Acton, who has taken her under his wing, and a dark friendship that seems to have the potential to ignite into romance.

The only thing more shocking than her family's rejection is the reason they want her leave. Her sister, Thalia, confesses that the town is inhabited by demons. Their mother believes that Acton is particularly dangerous and bent on revenge.

Ember knows her mother is crazy. But as she starts losing her memories and waking up to strange notes that she's left herself, she begins to believe her mother may also be right.
