You can guess from the title what this book is about, but there are still shocks and surprises to be had - think The Great Escape meets The Island set in the Basque country and you’re halfway there. It does have some lighter moments but doesn’t shy away from the inhumanity of war and can be emotionally draining. And be warned, there are a lot of characters, but go with it (make notes if necessary) and after the first 100 pages you’ll be hooked.
