Rob Dircks spent 20 years in advertising before writing his debut sci fi novel, Where the Hell Is Tesla? Result: Amazon listed Where the Hell Is Tesla? as its #1 time travel novel a month after it was published. (It’s actually an interdimensional odyssey comedy love story, but we won’t quibble with Amazon.) Audible lists Where the Hell Is Tesla as its #3 bestselling sci fi book behind The Martian and Andromeda Strain. Amazon and Audible review averages are above 4.
