John Wilker writes science fiction with a strong dose of humor, best known for the Space Rogues series that began in 2017. The twelve-book series follows Wil Calder and his crew of alien misfits as they take on various jobs across the galaxy, getting into trouble and talking their way out of it (or shooting their way out when talking fails). The books have a lighthearted space opera feel reminiscent of Firefly or Guardians of the Galaxy.
Beyond Space Rogues, Wilker has written The Grand Human Empire series, a five-book space opera with a different tone, along with the Expedition Inc adventure series and the Rogue Enterprises books, which continue in the Space Rogues universe. He is a self-published author with a consistent output, producing multiple books per year.
