DS1 has to read a WW1 or 2 related book over 5 weeks and review it. He mentioned "All quiet on the Western Front", Anne Frank's diary (no!), they've studied "Hitler's Canary" already, and there's "Boy in the Striped Pyjamas". I gather there are several Michael Morpurgo ones ("Waiting for Anya").
Any other ideas? I thought of "Schindler's Ark" (List!). Do you think that would be OK for a reasonably clever 13 year old?
"Biggles, Pioneer Air Fighter" - tongue in cheek suggestion, but he might enjoy reading it alongside a more 'serious' book to compare the different attitudes / approaches to dealing with war in fiction now and then!
