This book didn't quite grab me as well as the first books in the series. It's 2-3 years later, and the guys are still having roughly the same issues as they were having in the beginning. Points for consistency in the characters' personalities, but it did sort of make me cringe to watch the same issues over again, with the addition of medical problems. (It was obvious what direction that was going to take as soon as it was mentioned.) 
 Adding Dan's sister into the mix was a nice touch, though well before the end I was hoping Tatiana (Evan's sister) would wind up telling Krista off for what it really means to be family. (It didn't work out that way due to other events which occurred.) 
 So, I wasn't bored while reading. I read through it very quickly. But I was a touch ... disappointed? that it was roughly the same insecurities coming back up mostly. Which isn't really fair because it's definitely realistic. I just sort of wanted ... more than that. That's where the 1/2 star went. 3.5 stars. Not sure it'll have enough re-readability for me to round it up instead of down.
