Throttle is two master storytellers (King 2 and King 1) cutting loose and going balls-out, the way the father and son motorcycle team do in the story. Available as a Kindle single for $.99, Throttle is inspired by Richard Matheson’s classic screenplay, “Duel,” but its style owes a lot to Elmore Leonard’s fast-paced westerns.

The “throttle” here is not only the mechanism that delivers fuel to an engine, but the way parents sometimes feel when their kids screw up — you want to throttle ’em! This is a lean tale, but there’s still some meat; father/son relations, lives shaped by major disappointments and tiny triumphs, and the ever-stretchy bonds of love. But all of that is secondary to the action.  Throttle is a thrill ride that King and Hill keep as fun and punchy as a punk rock anthem.
