The Last Lecture is as good as it gets. Anyone who has watched Randy Paush's Last Lecture knows what the book is about. If you haven't, it' is about time you did. Go watch it. It's free and worth your time. I shall write a detailed blog sometime later. I intend to reread it.
Sidin's novels are good fun and I liked the subtle humour in the novels set around the lives of modern management consultants.
The Daughter of Time is an excellent novel that's old enough to be in public domain. All her novels are old enough to talk about calling exchange to connect the telephone, but are enjoyable any time.
Tales of Beedle the Bard is a children's book by J K Rowling, an offshoot from Harry Potter universe. As entertaining and stimulating as a children's book can be. ;-)
The Good Man Jesus and the Scoundrel Christ is a fictional story trying to clarify (or make sense of) another fictional story. ;-) Expertly done if you ask me.
The other four works by GRRM are set in the famous world of A Song of Ice and Fire - more popularly known as Game of Thrones - universe. As excellent as fantasy novels go. P&Q has lots of fantasy elements like dragons fighting etc; Dunk & Egg novellas are pretty thin on fantasy elements but have the same expert story telling and complex characters that GRRM is famous for.
 All her works are in public domain & available for free download here.
