4 stars 
 This was a cute if predictable romance. It's not my favourite of West by far (the Pivot Point series being my number one), but I enjoyed it well enough. 
 It was very easy to tell who Lily's secret pen pal was going to be. Our hero was the only male character (aside from Lily's family) that was fleshed out and interesting. 
 Warning: Minor spoilers ahead about said pen pal. But I think it is minor given it won't take you long to figure out who it is either! 
 Lily and Cade had an antagonistic relationship at the start. Cade did seem like a verbal bully when we first meet him through Lily's eyes. But by half way, through his letters and through his later actions I came to like him. We also learned most of what he did came from the right place. 
 Also it must be said: props to Kasie for writing clean YA novels (there is a little kissing and such, but the h and H never have sex in the books). Her heros are never true a**holes or players. Even Cade who have reasons to become an angry rebellious teenager with the cliche intimacy issue, wasn't anything like that. He coached a little league team, he could be really sweet. Once they came together he didn't try to push her away. 
 In terms of pacing, there was a bit of bickering and the story dragged a little in the middle. But West gave us enough to keep me reading. I didn't feel the need to put down the book and find another to read. The last quarter was West at her finest. Great witty conversations and great chemistry as the two finally clear up the past and their feelings. It left me smiling for the ending. 
 So for all that, 4 stars. 
 Safety warnings (view spoiler)[Safe. Read on if you want details: Both h and H date other people briefly, but nothing happens with the other W/M and not while/after they were involved together as a couple. The OW does try to cause problems but there is no big misunderstanding. (hide spoiler)]
