"When an Australian rare-book conservator named Hanna Heath finds a butterfly wing, a salt crystal, a white hair, and bloodstains in the recently rediscovered Sarajevo Haggadah, a late-medieval illuminated codex of uncertain provenance, she sets out to solve the mystery of the book’s origins. To her disappointment, analysis of the specimens reveals little.... Brooks, beginning where science leaves off, uses Hanna’s finds as entry points to richly imagined historical landscapes peopled by the Haggadah’s creators, protectors, and would-be destroyers—a female Muslim slave in Convivencia Spain, a Jewish doctor in fin-de-siècle Vienna, an alcoholic priest in seventeenth-century Venice. Their narratives alternate with Hanna’s own, and the final, multilayered effect is complex and moving." —The New Yorker
