Ready your engines, it’s down to the final racers. And it’s still anybody’s game. Quellex is determined to make this his most entertaining race of all time, and the drivers are in for more than a few curveballs. With each leg, the stakes accelerate: from pirate brawls to colossal wars to being transported to the far-future–they ll have to move fast before they re ancient history. But with their numbers seriously dwindled, hidden agendas bubble to the surface. In order to live through this, Alyson will have to cast that aside and put the pedal to the metal if she wants to win this race and change her past.
