"The journey continues as the crew of the Lost Light confronts a band of rogue Decepticons--with terrible consequences. Plus, a visit to the planet Hedonia--and chance to put recent events behind them. But all the while, locked in a secret cell underneath the Lost Light, hidden from the crew, a Decepticon psychopath is talking ... without opening his mouth. Rodimus and his crew are confronted by an enemy within--and not everyone will survive the encounter."--Page 4 of cover.
