Dennis Fletcher has a problem...or two. He's extra-smart, and even though he's skipped a grade, he's still bigger than a lot of the older kids! Making friends is hard—and something he wants more than anything.
When he invites two of his classmates over to work on a group project, they suddenly find themselves in the middle of Coronado's Conquistadors—and Dennis's execution is slated only a few days away! How did they travel back in time to the 1500's? And how are they going to get back to their own time before Dennis meets his end?
The pouch of special powder around his neck contains the answers—if only he can figure out how to use it to save them all and get them home to Texas—500 years in the future!
