(2) 4-6 How does a family live with recurring cancer? Would you want to know if you had that same cancer gene? These questions anchor a powerful verse novel in which twelve-year-old Cass copes with her dad's serious illness and her mom's relentless positivity, and counts on best friend Jayla's steady support. Weaving together genetic research, homeschooling particularities, Christian religious beliefs, and baseball fundamentals, Hill's portrayal of Cass's daily life is full of detail. Her inner monologue drives the story forward; free-verse poetry in a variety of forms relies on Cass's clear first-person voice and creative spacing for effect. Cass grapples with the decision of whether to be tested for the gene. Does she want to know the worst (or best) or does she want to live her life in fear and worry about the unknown? Her situation raises existential questions in ways that are palpable and relevant. Hill delicately balances deep sadness with genuine hopefulness in this distinctive and compelling novel.

(2) K-3 Illustrated by Ping Zhu. A snail possessing a rare left-spiraling shell is found by scientists and named Jeremy, even though it is not male but a hermaphrodite, like all snails. Jeremy not only has a "reversed" shell but its entire anatomy is flipped. This means Jeremy cannot mate with the overwhelming majority of snails because its reproductive parts won't line up with theirs. Popova skillfully employs metaphor to connect Jeremy's story to the underlying science of evolution, as in presenting the explanation of why snails, who can reproduce on their own, prefer to seek a mate: "because diversity is always lovelier than sameness, and because it makes communities stronger and better able to adapt to change." When scientists put out a call to the public to assist Jeremy in finding a partner with the "right" heart--a clever dual meaning--the search for sinistral snails turns up two, eventually allowing Jeremy to mate. Zhu's illustrations, filled with swirling expanses of color, brilliantly portray the concept of a recessive gene as a tiny but persistent snail silhouette inches across the pages and through geologic time.
