Infinity Ring Series

History is broken, and three kids must travel back in time to set it right! When best friends Dak Smyth and Sera Froste stumble upon the secret of time travel -- a hand-held device known as the Infinity Ring -- they're swept up in a centuries-long secret war for the fate of mankind. Recruited by the Hystorians, a secret society that dates back to Aristotle, the kids learn that history has gone disastrously off course. Now it's up to Dak, Sera, and teenage Hystorian-in-training Riq to travel back in time to fix the Great Breaks . . . and to save Dak's missing parents while they're at it. First stop: Spain, 1492, where a sailor named Christopher Columbus is about to be thrown overboard in a deadly mutiny!

Dak, Sera, and Riq might be in over their heads when they attempt to stop a Viking invasion! Hundreds of ships carrying thousands of warriors are laying siege to medieval Paris. The Parisians are holding their own, but the stalemate can only last so long. And that's bad news -- especially since Dak has been captured, forced to work alongside the Vikings while Sera and Riq defend Paris from within. No matter which side wins, the kids lose!

The multi-platform adventure through time continues! Dak, Sera, and Riq return to the United States and walk immediately 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.

THE END OF HISTORY Sera has a secret. She’s seen the future, and it is terrifying. Unfortunately, she can’t do anything to prevent the Cataclysm while stranded with Dak and Riq thousands of years in the past. Their only hope lies with the ancient Maya, a mysterious people who claim to know a great deal about the future. Is there more to these ancients than meets the eye?

Fix the past. Save the future. Europe is in the grip of the Dark Ages, but there is a light in the dark: Baghdad. The great city has become a center of learning, populated by scholars, merchants, and explorers from all across the known world. But danger lurks in the desert . . . and Dak, Sera, and Riq must act fast to save the world's greatest library from utter destruction.

Fix the past. Save the future. Dak, Sera, and Riq involve themselves in one of the most bizarre spy missions in history . . . and the outcome of World War II hangs in the balance.
