'Darkest Before Dawn' by Katie Flynn (Arrow Books, London, 2005) - another good read.
This revolves around the Todd family at the time of the 2nd World War. There is Martha and Harry Todd, with their 3 children, Seraphina, Angela and Eve (the first 2 names being very cherub-like names which was why the 3rd was called 'Eve' and not Cherub). You see the family go through various highs and lows in war time, with jobs and relationships etc. But the love and loyalty between them all remains strong, and finally we see Eve and Toby (after Toby originally went out with Seraphina) fall in love.
