Lincoln's story is, quite simply, riveting. I've read a lot of high altitude climbing literature and the quality varies - clearly, the authors tend to exhibit a high degree of proficiency in climbing, not necessarily in writing. Lincoln, however, is a rare breed - not only did he endure an incredible summit attempt, but he also has the tools at his disposal to accurately and engagingly portray the thoughts, actions and emotions involved in the process.
An incredible read, this book eschews the easy option of 'talking up' his own deeds, humbly setting the record straight, explicitly addressing concerns regarding climbing ethics, Everest climbing trends and the costs (emotional and financial) involved in climbing the world's highest mountain.
Highly recommended, highly entertaining, highly memorable.
