What's the Story?
History-loving Dak and science genius Sera are living in a world plagued by earthquakes and food shortages -- and a hyper-controlling government known as the SQ. When Sera is able to complete the time machine that Dak's scientist parents have been working on -- an invention called the Infinity Ring -- the fifth-grade best friends find themselves being called to a surprising new mission. A group called the Hystorians asks them to travel back in time to moments where history is broken to see whether they can right past wrongs and keep the SQ out of power. Their first stop: preventing mutinous brothers from taking over Christopher Columbus' ship.
Is It Any Good?
Kids will certainly be caught up in this adventure as two likable characters use their big brains to time-travel and stop a mutiny -- and hopefully save the world they're living in.
Author James Dashner covers a lot of ground here, explaining the Infinity Ring, the SQ, and getting Dak and Sera on their way to save Columbus. Some readers may get a bit lost trying to track exactly what's happening with time and what the breaks are all about; it's pretty sophisticated stuff. (One way the Hystorians know that time is broken is that some characters like Sera experience "Remnants," ghost-like memories that feel very real and leave them upset.) Even so, the author throws in enough humor, adventure, and inventive details -- like devices that let you speak and understand any language! -- to keep even reluctant readers engaged.
