When her two best friends dump her at the beginning of sixth grade, Lucy thinks that her life cannot get any worse, but then she discovers that she is about to get a new stepsister, spoiled television and music star Laurel Moses.

Lucy unexpectedly assumes the duties of the school advice columnist and offers up her best recommendations in the weeks leading up to the Sadie Hawkins dance.

Lucy tries to maintain her identity while running for class president, and deal with feeling neglected by her father and his pregnant girlfriend, especially when they plan to hold the baby shower on the same week as the election.

Lucy B. Parker has finally settled into her new life in New York City, living with her new frister (friend + sister), superstar Laurel Moses. She's got a new BFF in Beatrice, and she's spending her summer vacation off in L.A. visiting Laurel on the set of her new movie and meeting teen heartthrobs left and right. Life is good, until Lucy develops a crush-and unlike previous crushes, this one is not on a character in a book or a movie, but on a real living breathing boy, Beatrice's brother Blair. Unfortunately for Lucy, nothing ever seems to go as she plans. Because although Lucy dreamed that Blair would be her first kiss, it seems like someone else might beat him to it!

Lucy B. Parker has a problem. Specifically, everyone else's problems. When the advice columnist for her school paper has a little meltdown, Lucy's frister (that's friend + sister), teen superstar Laurel Moses, suggests that Lucy become the new go-to girl for advice! Lucy's not quite sure how that's going to work, considering she's usually the one asking for advice, but with the Sadie Hawkins dance coming up, it seems like everyone in her class needs some help.

After nearly a year of crazy, things have finally settled down for Lucy B. Parker. But then Lucy's mom and soon-to-be stepdad announce that they're finally getting married--in a month--and Lucy's life turns upside down. Wedding planning is hard enough, but when a reality TV crew ends up following the family around while it's happening, the results are disastrous. Can Lucy save her mom's wedding, and the family, or will everything fall apart?

Lucy B. Parker is running for class president! Sure, Lucy could let her frister (friend + sister), teen superstar Laurel Moses, campaign for her, but Lucy wants to win as Lucy, not as Laurel Moses' less-pretty-less- talented stepsister. To make matters worse, Lucy's feeling totally ignored by her dad and his girlfriend, who are preparing for their new baby. How is Lucy going to manage her famous frister, a soon-to-exist baby, and the campaign of the year all at once?
