Infinity Ring Book #1: A Mutiny in Time
by James Dashner
History is broken, and three kids must travel back in time to set it right!
When best friends Dak and Sera 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. Now it's up to them 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!
