I made myself let go of my issues with the premise (with Facebook etc it's hard to believe these girls could pull this off; and while I know high level athletes have an easier time with transitioning to other sports than normal people, I had a hard time believing The Sloanes would do as well as they did) and once I did, I quite enjoyed it. This reminded me quite a bit of Jennifer Echols' earlier book (Major Crush, Ex Games), which I mean as a compliment, since I really liked those books. 
 FWIW, this is one instance where the alternating POV makes loads of sense--and it's executed very well. I'm really hit or miss with that narrative style, but it works here. 
 Anyway, this is a pretty fun read and I'll write more in a couple months when it's out,
