Mission Unpopular is full of typical middle school drama and the timeless quest for popularity. Margot is an endearing character, though definitely not perfect, and she makes many mistakes while trying to be accepted and deal with friendship issues. Some mean girl behavior and mean spirited pranks get taken too far, with one incident resulting in a broken leg and another landing a girl in the hospital after ingesting poison. On a positive note, lessons are learned and amends are made. Language is mild (d-mn, bad-ss, b-tchy, scr-w you) and characters flip one another off. Lying to parents takes place often and main characters are involved with shoplifting. Tween girls who have dealt with feeling alone and unpopular at school, dealt with friendship troubles or dealt with step-parents and/or half siblings will thoroughly enjoy this book about a girl trying to survive seventh grade.
