When a young girl’s grand­par­ents come for a much antic­i­pat­ed vis­it from Cana­da, a care­free vaca­tion takes an unex­pect­ed turn. Over the course of one after­noon, Grand­ma final­ly tells her grand­daugh­ter the truth about the mys­te­ri­ous num­ber on her arm and her expe­ri­ences dur­ing the Holo­caust. Based on the true life sto­ry of the author’s grand­par­ents, both Holo­caust sur­vivors, The Num­ber on Her Arm shows how some­times those who endure the worst fates in life come out the strongest.
