In her debut chapter book, Platt shares the story of a young girl navigating friendships and the challenges of trying to win her school’s science triathlon.

Young Parker Bell is a curious child who loves science and aspires to match up to Mae Jemison and Jane Goodall one day. Her best friend and partner in science is coding whiz Cassie Malouf. They have been best friends since kindergarten, but Parker gets jealous when Cassie suddenly starts becoming friendly with Theo Zachary, a shy boy in their class. Parker worries that Cassie likes Theo more than her, and she fights hard to keep her friend. Matters only get worse when Cassie invites Theo to be part of their team for the science triathlon, which features a science trivia contest, an egg drop, and a presentation. In a somewhat predictable plot, Parker realizes she has a lot in common with Theo as she spends more time with him. Platt works hard to defy gender stereotypes. In addition to the girls’ STEM enthusiasm, Parker’s mom teaches phys ed, her dad owns a bakery, and Cassie’s mom teaches math. Zhai’s simple black-and-white illustrations of Parker, Cassie, and the classrooms provide a good visual aid to the story, depicting Parker and Theo as white and Cassie with dark skin and long black hair.

A lighthearted read that will offer comfort to young children that others too face challenges of friendship, teamwork and competition.
