From the review:
"The forensic details of manuscript analysis are far more interesting and subtle than Hanna’s personal evolution. How did the Haggadah pick up a wine stain, cat’s hair or saltwater mark? How did it lose the silver clasps that are notable by their absence? Each of these questions has a chapter, and these puzzle pieces are interspersed with segments devoted to Hanna. Every historical sequence is filled with danger, oppression and high drama."
