This Thing Between Us by Gus Moreno

A truly scary "Alice down the rabbit hole" look at a grieving man whose life has been taken over by a smart device. We have all had those creepy moments when Alexa decides to turn on for no reason at all and laughed it off. Thiago thought the strange voices, lights and music randomly coming on through their smart device was laughable until his wife is killed and he runs away to a cabin near Rocky Mountain National Park to grieve in private. Going to a remote location was his first mistake. A series of scares happen as well as the appearance of a strange wall (like the one in 2001 A SPACE ODYSSEY, a CUJO like dog, zombie like encounters and really weird dreams push him to the edge of sanity that even his well meaning mother-in-law can't help with. This is raw grief inspired psychosis mixed with a futuristic fear of evil technology and a good old fashioned horror story. Fans of HORROSTOR, vintage Stephen King and NIGHT OF THE LIVING DEAD are all worthy readalikes. This will be your go to Halloween horror read!  4 stars
