<spoiler > What on earth did I just read ? This started so well - the main character dealing with grief , death and trying to cope . It then morphed into some techno-horror where the smart device did weird things leading to his wife’s death . 
He couldn’t cope with the fallout of her death , so he packs up and moves to a cabin in Colorado . 

Which is where I start losing it - there are some other worldly things happening , some wall appearing , murder , resurrections , zombies , Mexican gothic rituals - all told in a crazed fever dream . The ending is so abrupt and make-what-you-can-of-it . It’s completely open to interpretation. This had potential but toward the end , just reads like garbage and nonsense . 

Thankfully this was a short read  </spoiler >
