Callsign: King II – Underworld (Chesspocalypse #4)
by Jeremy Robinson & Sean Ellis (2011)
Strange things have always happened in the Superstition Mountains of Arizona… Bizarre lights, reports of cave entrances that appear and then vanish, hundreds of mysterious disappearances…and rumors of monstrous creatures that inhabit a labyrinthine underworld.
When a terrifying accident on an Arizona highway leads to a military exclusion zone and a cover-up of staggering proportions, Jack Sigler—Callsign: King, field leader of the elite and ultra-secret covert Chess Team—joined by his closest friend, archaeologist George Pierce, sets out into the desert, intent on discovering the truth.
This follows Jack Sigler from episode 1: Callsign King. Here he takes on subterranean monsters, weird science and an assassin.
Like the first in the series, the pacing is fast and furious, talk is minimal and plenty of action. There is a rather absurd premise of “free’ energy that provides the basis for the story. But not to worry, Jack will overcome everything with a measure of experience and plenty of luck. Keep ‘em coming Mr Robinson !!!
