In honor of Presidents' Day, A.J. and Andrea from Ella Mentry will compete against their Dirk School rivals in the ultimate Presidents' Day Challenge! The winning school will get bragging rights, a free trip to an amusement park, and a top-secret prize.

The only problem is that A.J. doesn't know anything about U.S. presidents, unless it involves their use of toilets! Will A.J. and Andrea be able to work together as a team and bring home the win?

Bestselling author Dan Gutman brings his kid-friendly sense of humor to this special series of after-school chapter books featuring hilarious stories plus thirty-two pages of games, puzzles, and more.

This is one weird Presidents' Day special you won't want to miss!
