I don't really read blurbs or marketing before choosing what to read anymore, I've found that I get greater enjoyment if I enter a book without any preconceived notions. So the central conceit of When We Were Real (which is explicitly laid out in the jacket copy) came as a complete surprise to me. 

Me: Oh, this kinda has Ubik vibes. 

Character in the book: [explicitly mentions Ubik]

Me: Welp, there you go. 

This was absolutely delightful, and I will probably be reading it again before too much longer.
