Just found this thread. Love all the suggestions and have noted them for my next bookstore or library visit. I am also a fan of the Shopaholic Series and Alexander McCall Smith detective books. I have some additonal suggestions:
Our Hidden Lives by Simon Garfield which is a compilation of diaries from post-war Britain, a very interesting read. Also, I love the Philipa Gregory historical fiction books, The Other Boleyn Girl, The Queens Fool, etc. Slightly off topic, but if you know anyone who loses a beloved dog, the following book is a wonderful little gift you could send to the bereaved owner, The Last Will and Testament of a Very Distinguished Dog by Eugene O'Neill. I received this several weeks ago and it was a poignant book that will make any dog owner feel a bit better after they lose their beloved companion.
Cheers, Pam
