Full content visible, double tap to read brief content.

Jacob Holo has been a recreational geek since childhood, when he discovered Star Wars and Star Trek, and a professional geek since college, when he graduated from Youngstown State University with a degree in Electrical and Controls Engineering. He started writing when his parents bought that “new” IBM 286 desktop, and over the years, those powers combined to push him to the next level of nerddom: a sci-fi author who designs intricate worlds and tech systems...and promptly blows them up in a string of nonstop action.

He is the author of nine books, including national bestsellers The Gordian Protocol and The Valkyrie Protocol (with David Weber), military sci-fi novel The Dragons of Jupiter, YA urban fantasy Time Reavers (a Kirkus Reviews Best Indie Book of 2014), and the mecha space opera trilogy Seraphim Revival (Bane of the Dead, Throne of the Dead, Disciple of the Dead); YA steampunk fantasy The Wizard’s Way (with H.P. Holo), and GameLit fantasy Monster Punk Horizon: Excess (with H.P. Holo).

Between novels, Jacob enjoys gaming of all sorts, whether video gaming, card gaming, miniature wargaming, or watching speed runs on YouTube. He is a former-Ohioan, former-Michigander who now lives in South Carolina with his wife/boss H.P. and his cat/boss Nova.
