Alone on the Wall by Alex Honnold (2016)

Alex Honnold's book, written in collaboration with

David Roberts, of "Mountain of My Fear" fame. 

This book covers Alex's early career climbing and most of his big solos prior to his climb of Freerider on El Capitan. However, book was published before Honnold pulled off that most famous solo, and thus, does not discuss it.

Paperback copy, 248 pages, text with a black and white photo insert in the middle.
