A thouroughly enjoyable book! Had some LoLs in the beginning of the book. Love the nerdiness of it. My attention started to flag near the end of the book. The author lost my attention there, and at the end, I had to rewind some minutes because the ending is abrupt.
All the Bob-versions were awesome, the premise is great. Now please, keep up the good writing, as in: the good writing from the start of the book, not the boring writing of the end. Writing endings is a particular skill in writers, and not all of them are good at it (for example, Neal Stephenson really sucks at it). But it is something you can practice.
So, I'm looking forward to more Bobbiverse!
