(2) 4-6 Arthur Popper is a diffident, slightly anxious eleven-year-old who lives with his parents and younger sister above the family business, a thriving, capacious secondhand store in Boulder, Colorado. He works shifts in the store and is valued for being "good at customer service" but longs for another area where he can truly shine. When some family members' and friends' jewelry starts disappearing, he takes on the mystery-solving challenge. He receives advice from a ghost mouse who lives in a teacup on his bookshelf, the single touch of fantasy in an otherwise naturalistic novel. The detective narrative, which is tidily composed and plausible, provides the scaffolding for a story of family and community relationships that is a tour de force of small, beautifully calibrated effects. Arthur's best friend is Veda, who is Latinx, but things go sideways for them when Arthur's grandfather expresses a prejudice against "certain kinds of people." Freeman doesn't provide easy answers to the problem of a bigoted family member, nor does she give Grandpa an easy epiphany. Instead she portrays a realistic, flawed family with all its tensions. She allows Arthur to encounter and grapple with the concept of white privilege on his own, in age-appropriate terms, keeping the focus firmly on the child characters and their strengths.

(2) 1-3 Illustrated by Paula Franco. Even though the titular sisters first seen in Twig and Turtle: Big Move to a Tiny House (rev. 7/20) have now settled into their home in Happy Trails, Colorado, they still have a couple of crises to solve. The owner of a new toy store initiates the story's action by announcing a naming contest. Twig is at first reluctant to reduce her chances of winning by telling her friends about the competition. Although the situation resolves itself, the idea of tension between what she wants to do and what she should do is born. Later, when Twig accepts a doll from a friend and thus breaks their household's five-toy rule, she lets a "big old mountain of want" dictate her actions. Jacobson again shows her strength in creating problems seemingly specific to one setting but experienced by many children; without a hint of didacticism, she allows Twig to reach a creative ­solution to the problem. Short chapters, generous use of dialogue, and text-­supporting spot art scaffold the reading for newly independent chapter book readers. This series ­reaffirms the old adage that good things come in small packages.

(3) YA This intricately plotted, irony-heavy thriller alternates between two narratives: one from the perspective of the title character, who's hell-bent on finding and killing her younger sister Mattie's murderer; and one that's the transcript of a Serial-like true-crime podcast that starts after Sadie's car is found abandoned. The narratives work in tandem to create a suspenseful picture of a brave young woman with a traumatic past.
