This book on the 5-year journey of the Beagle round the world, with Charles Darwin on board as a 22-year-old naturalist is actually developed from a film treatment which Moorehead wrote. Thus, it is rather light on the details. But it will appeal to readers who want a general introduction to the journey of the Beagle and the exploits of a young Darwin.
This book is also illustrated by paintings from contemporary sources and thus will appeal to readers who are looking for an illustrated version of the journey. Readers looking for a more detailed illustrated version should look at Charles Darwin On the Origin of Species Illustrated Edition by David Quamman.
