Beginning with the Worst Days series in 2007, Walker has been a misanthropic favorite in the short form gay erotica world, writing under the pen names wanderwonder and acerbicscribbler, among others. His experiences of living and working outside the U.S. often influence his writing. He makes his own cover art, and it is terrible. Though he doesn't like people very much, he loves his half German Shepherd, half German Wirehaired Pointer pup.
