Ex-Mas by Kate Brian
(Sorry for the short review; I don't think there's that much to talk about)
This is the story of Lila and her ex-boyfriend Beau. If you have ever read a romance or seen a romantic comedy movie, then you can probably figure out what happens in the story.
I had some problems with Lila as she is largely unsympathetic (although her younger brother is also incredibly annoying, at least to someone who is an older sister) in the beginning. That is, she is a vapid popularity-obsessed bore with the requisite college boyfriend who is of course cheating on her (why can't the college boyfriend ever realize they're just too different? Why are they so focused on having their cake and eating it too?) Then there's Beau, the musician Mr Anti-popularity who has matured considerably in the three years since their falling out. He was okay; I've read dreamier heroes.
Overall: 3.5/5 for complete predictability and not very engaging characters.
