Time has gone wrong, and best friends Dak Smyth and Sera Froste, together with the young Hystorian Riq, must use the infinity ring to travel back to one of the Great Breaks--a mutiny on the Santa Maria--to correct history and defeat the SQ.

Friends Dak, Sera, and Riq use the infinity ring to travel in time to medieval Paris where Viking warriors are attacking the Parisians. While Sera and Riq are defending Paris, Dak is captured and forced to fight with the Vikings.

Dak, Sera, and Riq return to the United States and walk right into a deadly trap. The year is 1850 and the nation is divided over the issue of slavery. In these dark days, the Underground Railroad provides a light of hope, helping runaway slaves escape to freedom. But the SQ has taken control of the Underground Railroad from within. Now Dak and Sera are left wondering who to trust...while Riq risks everything to save the life of a young boy.

Dak, Sera, and Riq find themselves stranded thousands of years in the past and their only hope is the Mayas who know a great deal about the future.

As thousands of Viking warriors attack Paris, Sera, Riq, and all the people of the city struggle to defend themselves and Dak remains a prisoner, forced to work for the invading army.

They've sailed on the Santa Maria, defended famous cities from Vikings and Mongols, and come face to face with some of the greatest figures in history. Now, at long last, Dak, Sera, and Riq travel back in time to the moment it all began. Their mission: to save the life of young Alexander the Great. But they are not the only time travelers in ancient Greece. An epic battle against their most dangerous foe awaits them, and history will be written by the victors. Fix the past. Save the future. It's now or never!.

Dak, Sera, and Riq have fixed the Great Breaks in history, but SQ is not beaten yet, and the biggest, boldest Infinity Ring adventure of all time has just begun.
