Robyn Bennis works in biotech but dreams of airships. She lives in Mountain View, CA, within sight of the historic Hangar One at Moffett Airfield. The Guns Above is her debut novel.

K.B. Wagers is the author of the Indranan War trilogy and the forthcoming Farian War trilogy, about the gunrunner empress Hail Bristol.

They live in the shadow of Colorado's Pikes Peak with their partner and a crew of poorly behaved cats. They're especially proud of their second-degree black belt in Shaolin Kung Fu and their three Tough Mudder completions. There's never really a moment when they're not writing, but they do enjoy fountain pens and good whiskey.
