I'm reading How to be Brave, by Louise Beech. It was obviously one of their deals as it's full price now.
It's good; a 9-yr-old newly diagnosed with diabetes, her dad away with the army and how she and her mother cope.
Intertwined with the story of the mother's grandfather, who was on a cargo ship that was torpedoed during the war.
Funny with kindles isn't it Jo, the batteries last so long you forget about it until you can't read any more
