RU Level: 6th Grade
After Suzy sneaks aboard a train that mysteriously steams through her living room, she becomes the newest "Postie" who delivers unusual things to Impossible Places. When she finds one delivery is actually a boy trapped in a snow globe she takes him back on a whim and begins a chase that leads to some unexpected consequences with the fate of the Union in her hands.
Don't get bogged down with the physics references at the beginning, if that isn't your thing, because the action then starts to accelerate-- like a runaway train! Great for girls who like fantasy and take-charge attitudes.
