Kessler (When the World Was Ours) intertwines two poignant stories via four alternating perspectives in this well-paced novel: one of Dutch Jewish sisters Mila, 12, and Hannie, 15, posing as Christians in WWII Amsterdam, the other of contemporary British 13-year-old Liv, who’s navigating friendship troubles and her relationship with her cold, secretive grandmother. A school assignment to create a family tree stumps Liv, who knows nothing about her ancestry. But after her widowed paternal grandmother, Bubbe, moves to a care facility, Liv cleans out her attic and discovers a photograph dated 1942 that might provide clues to Bubbe’s guarded nature—and help with Liv’s assignment. Hannie’s unsent letters to her mother are interspersed throughout Liv and Mila’s dual POVs, and occasional later chapters are narrated by another Jewish child in Amsterdam. Narrative parallels between Liv’s efforts in standing up to bullies and Hannie’s work saving Jewish children with the Dutch Resistance feel some- what unevenly weighted, but skillfully structured suspense as well as Liv’s persistence in learning—and helping complete—Bubbe’s story makes for a rewarding read. A historical note concludes. Most characters present as white; many are Jewish. Ages 8–12. (May)
