The Mystery of Everett Ruess by W.L. Rusho (updated 2010). A writer and artist, Everett Ruess disappeared in 1934, age 20, in the American Southwest. Most of Rusho's book is a compilation of Ruess' 1930-1934 letters to his parents, older brother, and friends. Ruess' block prints and Rusho's photos provide a backdrop to Ruess' descriptions. While interesting to read, Ruess' thoughts and actions reflect his extreme youth.
The Last Season by Eric Blehm (2006). Exploration of the life, career, and line-of-duty disappearance, in 1996, of Sierra backcountry Ranger Randy Morgenson. Fortunately for Morgenson's widow and friends, his remains were found five years after his death, so at least they found a closure denied to Ruess' loved ones.
Dancing with Myself by Billy Idol (2014). Hearing certain Billy Idol songs transports me immediately to one of my favorite weekends, high school French and Spanish Clubs joint trip to Chicago in October 1986. Sweet memories! Idol's autobiography doesn't disappoint--plenty of hard living, good music, and memorable moments. Recommended for any fans of his '80s music.
