Aviva and Holly, two 12-year-old girls, discover that they are identical twins. Each was adopted; their parents weren't ever told that their daughter had a twin. When both girls volunteer to help with a December holiday pageant, they meet by chance ading to many questions and an immediate bond. Both are conflicted about the pageant: Aviva doesn't feel "Jewish enough" to be the only kid representing Judaism in the show; Holly promises Aviva to sing with her onstage, but suffering from stage fright, she dreads performing. Vivacious Aviva aims for onstage glory, while Holly hopes to become a writer. Holly and Aviva narrate alternating chapters. Much of the action takes place when the twins secretly switch places for several days to better understand each other's families and their December holiday celebrations. The ending is as predictable as that of a Christmas-themed rom-com and just as enjoyable for tweens. Meyer, who usually writes for teens, and Levy, who writes middle-grade fiction, offer a lively, engaging narrative.

Gr 5 Up— A tale of two girls from different families who meet and determine they are identical twin sisters. Aviva Davids has always known she comes from a blended family; she was adopted at birth by a Jewish mom and a Protestant father and enjoys an outgoing life with her two brothers. She feels closest to her Jewish grandmother and wishes her family celebrated more religious traditions—she even insists that her family celebrate Hanukkah this year. Holly Martin, who's also an adoptee, lives with her overworked mom, elderly grandfather, and pet cat. She leads a quiet life, loving to read and write stories. She is looking forward to getting a Christmas tree and celebrating the holiday. When Holly and Aviva meet at a talent show rehearsal at a local retirement center, they are shocked at their similarities. They realize they must be twins and want to learn more about each other's traditions and family members. Aviva learns that families can be quiet and subtle, while Holly learns all about Jewish traditions. After a few days of living with each other's families, the girls reveal their true identities at the talent show. Once the shock wears off, both families are delighted and surprised that they didn't know that the daughter they adopted was a twin. VERDICT Meyer and Levy bring warmth and depth to the classic separated-at-birth trope with this gentle story. Recommended for tween fiction collections.— Charla Hollingsworth
