I suspect this may be a case of blame the reader, not the book. I enjoyed some of the stories, but others didn't work as well. Each new story I had to force myself to start reading. I may try again if my library gets a physical copy, which would be easier for me to dip in and out of around other reads!
Some of the stories were really strong, so if the premise interests you don't let my bail put you off (but I'd recommend a borrow, not buy)
