The Times: Thriller Books of the Year

When a Jewish classmate is attacked by bullies, fifteen-year-old Nico just watches - earning him a week's suspension and a typed, yellowing manuscript from his frail Nonno Paolo. A history lesson, his grandfather says, and a secret he must keep from his father.

Nico is transported back to the Venice of 1943, an occupied city seething under the Nazis, and to the defining moment of his grandfather's life: when Paolo's support for a murdered Jewish woman brings him into the sights of the city's underground resistance. Hooked and unsettled, Nico can't stop reading - but he soon wonders if he ever knew his beloved grandfather at all.
