Operation Mincemeat: The True Spy Story That Changed the Course of World War II by Ben Macintyre is a book I recommend to many and also Sherlock Holmes, excellent writing!1

Damn, most people haven't heard of The Alchemist (if you mean the Secrets of the Immortal Nicolas Flamel series). So I usually suggest that.
I guess Chronicles of Narnia, the books are great, but maybe only if you first read them when you're younger... I still think they're great though.
House of the Scorpion, and the sequel The Lord of Opium (by Nancy Farmer)
