Thomas Jefferson and the Return of the Magic Hat — Deborah Kalb

After almost six months in Maryland, fifth-grader Oliver still misses his friends back in New Jersey. But things start to change one day, when his neighbor—and possible new friend—Sam lends Oliver a magic hat that takes him back to the 18th- and 19th-century world of Thomas Jefferson. Oliver and his sisters—Cassie, the nice one, and Ruby, the annoying one—end up learning more about Jefferson than they'd expected. And Oliver finds that his new neighborhood might not be so terrible after all. Thomas Jefferson and the Return of the Magic Hat is the third in The President and Me series that began with George Washington and the Magic Hat and John Adams and the Magic Bobblehead. This new adventure brings back previous characters Sam, Ava, J.P. (blink and you might miss them, though!), and of course the cantankerous talking hat itself.
