GUARANTEED: This is a writing partnership I can get on board. Bring on the sequels, prequels, whatever may come-quels! You've just won a new fan :) 
 Okay - that's a lie. I've read Penny Reid and L.H Cosway before, and given at least four or five star ratings (and also three) to them independently. I think Reid is a biochemist and Cosway a English Lit graduate. These ladies know what they're doing, and are very intelligent :) 
 This book was awesome. 
 Lucy with her rainbow dyed hair, is a kleptomaniac and has a compulsion to steal, to make up for her over-critical mother. Enter Sean, a guy who commits to a lot of one night-stands, but leaves his ladies wanting. Lucy tutors Sean to become a better lover - and man, were those scenes hot as fuck. Also the extended cast - Ronan, Annie, Broderick...awesome, man. 
 If I were to have one complaint - especially in the beginning, I saw two different styles of writing not blending as well as I'd have liked. Like I was totally in Lucy's headspace. Strong beginning. Flaws of the character laid out there. Just like that. Then we jumped to Sean...and I was irritated I still wasn't with Lucy, because Sean appeared more wishy-washy and his voice wasn't as strong. But it doesn't matter - because it all became the same to me, and I loved it anyway, though sometimes I'd feel super immersed in the story - and other times I felt like I was not reading the "same voice." Which is super confusing, because Sean and Lucy ARE separate voices - no what I mean, is I'd be reading Sean (or Lucy's) voice - and halfway through, I'd detect a distinct shift in style and tone. Like writers were switched midway. Ehhh...I don't know, maybe it's all in my head. It doesn't matter too much anyway, because their styles compliment each other! 
 Fantastic, sports orientated book. Can't recommend it enough!
