Cami and Isa are very different sisters.

Cami always wants to be perfect. She worries about it every single day! She follows all the rules, does all her homework on time, and never makes a fuss.

Isa, on the other hand, is confident everything she does is perfect, even when it’s most definitely not. Her drawing on the wall? Perfect. Her bowling ball bouncing into the other lane? Perfect-er.

When the two sisters face their own challenges at the first day of basketball camp, they realize there’s a lot they can teach each other. Featuring charming and humorous illustrations, The Perfect One shares gentle messaging about the importance of patience, practice, and supporting your siblings.

The perfect book for kids struggling with perfectionism, or any child that compares themselves to a sibling, The Perfect One helps children understand there’s no such thing as perfect—just being perfectly true to you.
