The world is on the edge of destruction, and the only hope is to go back in time to go back in time and fix things that shouldn't have happened. The Historians send Dak, Sera, and Riq to fix time after the SQ attacked their HQ and the first stop is in Palos de la Frontera in Augest 3, 1492.

When they find a historian (aka: Gloria) she tells them that Columbus and the Amanico brothers are leaving to a "new world" which is the break.Once on the ship with Eyeball, they find out that the Amanico brothers are past SQ agents who want to kill Columbus. After fixing the break, they get transported to 1775.

Recommendation

I would not recommend this book unless you are a history person and want to try to picture and alternate reality than ours.

Moral

Climax

The climax was when Eyeball turned out to be a Historian and when there was a pirate battle between the ship crew and the passengers over ship.

Theme

The theme of this book is a mixture between action and adventure.
