Lindsey Dunn is looking forward to seventh grade. Her blended family-including her mom, stepdad Chris, and two awesome but annoying little step-siblings-is really starting to bond; her best friends Emma, Destiny, Erin Lee and Hailey are awesome. The only thing is, Hailey seems really distant sometimes. She's become friends with a new girl who doesn't really click with Lindsey. And when that girl starts to ruin her school year, Lindsey has to make possibly the biggest decision of her life.
