Edited May 24 because I didn't read the rules properly about needing to have two books that aren't part of another challenge!
1. The No. 1 Ladies' Detective Agency by Alexander McCall Smith
2. Cocktails for Three by Madeleine Wickham (aka Sophie Kinsella)
3. 21 Proms edited by David Levithan and Daniel Ehrenhaft
4. Second Chance by Jane Green
5. One of those Hideous Books Where the Mother Dies by Sonya Sones
