Query: A Biography for teenagers

This book is for teenagers, it is presented in a very younguish context with illustration and large print. Amazon should actually classified as a children, teenagers reading material. Actually teenagers do not read this type of books anymore, I used to read them in the 70's. Very dissapointing considering I am a serious reader looking for info on a more detailed and technical manner.
