Just like 99% of the Earth's population, I thought all Sir A. C. Doyle has written are mystery novels, especially that of Sherlock Holmes short stories and novels. Picking this up in the library, I was pleasently surprised by this story.
It's a story of a band of adventurers going to an undsicovered part of the Amazon where dinosaurs still exist. It has moments of trial and tribulation, high adventure, and pure child-like wonder.
This book is a great adventure novel, more geared towards a younger audience, but adults will enjoy this nonetheless.
