Astrid, a spunky, smart California third grader, has great aspirations.

She will become “the first astronaut with hearing aids,” a possibility that is treated very naturally within this story, the first in a new chapter book series. Joining the Shooting Stars, an after-school club devoted to all things space, has long been part of Astrid’s “Astronomically Grand Plan.” Though Astrid wants to go to space camp, it’s expensive, but a scholarship is available for the Shooting Stars student who earns the most points for completing the STEM-oriented Astro Missions. She discovers another problem when she realizes that her best friend, Hallie, is more interested in art than in STEM and joins the Petite Picassos club. How can Astrid navigate Shooting Stars without her BFF, especially when she and her teammate Veejay don’t start out well? Club teacher Ms. Ruiz stresses creativity and partnership, and math and science enthusiasts will be attracted to this book, but the real emphasis is on relationships. Astrid must befriend Hallie again after voicing her disappointment with her interests and learn to be a good teammate. Astrid is likable, and her story, told in first person, realistically explores her hearing issues, her initial problem-solving failures, and her successes. Black-and-white illustrations depict Astrid (wearing her hearing aids) and her family as light-skinned, though other students appear to be racially diverse, and Hallie is cued as Asian.

Using science and technology, third-grader Ada Lace kicks off her new series by solving a mystery even with her leg in a cast.

Temporarily housebound after a badly executed bungee jump, Ada uses binoculars to document the ecosystem of her new neighborhood in San Francisco. She records her observations in a field journal, a project that intrigues new friend Nina, who lives nearby. When they see that Ms. Reed’s dog, Marguerite, is missing, they leap to the conclusion that it has been stolen. Nina does the legwork and Ada provides the technology for their search for the dognapper. Story-crafting takes a back seat to scene-setting in this series kickoff that introduces the major players. As part of the series formula, science topics and gadgetry are integrated into the stories and further explained in a “Behind the Science” afterword. This installment incorporates drones, a wireless camera, gecko gloves, and the Turing test as well as the concept of an ecosystem. There are no ethnic indicators in the text, but the illustrations reveal that Ada, her family, and bratty neighbor Milton are white; Nina appears to be Southeast Asian; and Mr. Peebles, an inventor who lives nearby, is black.
