Infinity ring book 8

Dak Smyth and Sera Froste are heroes. They fixed the Great Breaks in history, setting the world on its proper course at last. Or did they? Strange things are happening in the present, and it all points to more trouble in the past. But the time travelers have no idea why the SQ is so interested in a Chinese alchemist, the trial of Galileo, or a Russian dog named Laika. With the clock ticking and no Hystorians to help them, this time Dak and Sera may not be able to fix what has been broken. . . .

The book comes packaged with a full-color, two-sided, collectible Hystorian's Guide, a player's strategy guide to the online adventure.

Follow the map, study the Guide, and save history!

Episode 8:

Hystorian Training

Do you have what it takes to stop the SQ?

Being a Hystorian is hard work, and takes years of training. If you want to test your prowess or hone your skills, this is the place to do it. For Hystorian vets looking to take your abilities to the next level, or new recruits wanting to see if you can cut it, Hystorian Training will give you a taste of some of the action and adventure time travel has in store.

Use all the tips, hints, and riddles on your Hystorian's Guide to challenge yourself!
