I read “Ghosts of Everest, The Search for Mallory and Irvine," by Jochen Hemmleb, Lrry A. Johnson and Eric R. Simonson.
This book documents the expedition which found Mallory’s body high on Everest in 1999. It also gives good coverage of the basic info available about Mallory and Irvine’s climb and possible scenarios as to what happened.
It is not comprehensive but has great pictures and is a good read. Also, it includes a good set of footnotes, a detailed appendix of Mallory/Irvine expedition statistics and a list of selected references if you want to dig deeper.
