Childhood crushes, silly girlish fan clubs and that guy you secretly love to hate... and love. An long ago elementary school crush turned feud gets a little more interesting when Zach's widowed dad and Chloe's single mom fall in love and get married. Suddenly, the two warring college students are thrown together more often than they'd care to be as step-siblings. However, determined to be civil for the happiness of their parents... and they might just discover that they don't dislike each other as much as they originally thought. Maybe.Overall, while I wish the character development had been a bit more solid, and some of the situations seemed a tad contrived, The Unofficial Zack Warren Fan Club is a sweet, feel-good read, summer read.
