I loved this book right up until the end. Then I wondered what happened to the rest of the ending. I wanted to see the confrontation with the in-laws. I wanted to know if there was an explanation of James to Evan. I wanted to know Evan's reaction to Matt's sudden mid-life-crisis change in apartment and job to school. I wanted to see them figure out something more than grinding into each other. Just disappointed with all the things that were missing at the end. So, it was going to get 4 stars, and I dropped it to 3.5 stars, rounded down to 3 for GR. 
 I'm curious to know if we will see the fallout of Matt's call to James, answered by his roommate/best friend. That's my next read.
