Grim Reflection

Ghosts are real.
Shay and her friend Max are filming a podcast in a haunted house when things go horribly wrong. A spooky house turns out to hold an entity that can not only touch Shay, but tries to drag her into an antique mirror.
Trouble escalates when her brother is seemingly possessed and disappears. Someone, or something, is riling up and gathering ghosts in the little town of Teton Falls.
Shay, with the help of friends and new acquaintances, has to solve the mystery of who, or what, is responsible for this paranormal activity - before they destroy the town and everyone she cares about.
Fans of The Taking of Jake Livingston and Lockwood and Co. will love this debut from A. Lawrence.
