Donald Jeffries was inspired by a diverse and ecclectic group of authors like Charles Dickens, Madeline L'Engle, Edward Eager, George Orwell, Kurt Vonnegut, Bram Stoker, Charles Fort and Ambrose Bierce. The Unreals was published in 2007 and has been compared to the television shows The Twilight Zone and X-Files, as well as the classic fairy tales The Wizard of Oz and Alice In Wonderland. 

Jeffries has spent many years researching the assassination of John F. Kennedy and other significant historical and political events. Various conspiracies and unexplained, fortean-style phenomena play a strong role in his writing.
