I want to start off by saying how refreshing it is to read about protagonists who are elderly. There is quite a bit of time-hopping, yes, but much of the narrative takes place in modern day. It was interesting to see the characters take on the supernatural when they are weak and feeble, as opposed to young and able bodied. 
Mr. Friendlyman is a truly distressing villain, and there is some imagery in The Home that will stick with me. I didn't realize how cosmic the story would get, and I was pretty delighted with that. The only thing that knocked my rating down was the ending. So much information is revealed that I wish had been expanded upon, and I felt it ended super abruptly, almost confusingly so. I still absolutely recommend the book and rate it 4.25 stars.
