When your mother walks out on you, you can't stand your dad's new girlfriend, and boys are (almost) nothing but trouble, sixteen's not so sweet.

Marcie's life is a mess. At least she thinks it is. Her father's latest girlfriend keeps meddling in her business, her younger brother Kyle has turned into a neat-freak since their mother walked out on them four years ago, and her best friend Callie is going off the rails.

Things don't get any better when Marcie's mother announces she's getting married. She hasn't wanted to see Marcie and Kyle for the last four years, why does she now want them to spend the entire summer with her?

As first love hits, Marcie finds out what's really wrong with Callie, and near-tragedy strikes the family. Marcie suddenly has some tough decisions to make.
