Eight-year-old Harriet Butler is not really lonely-her housekeeper is a hoot and her dad's awfully nice-but she lost her mom when she was little. The last thing Harriet expects is to meet a space alien on vacation from another planet! But one morning Wiz (as she names him) appears in her father's wheat field disguised as a hare. Proving to be a wonderful friend, Wiz turns Harriet's summer into one that's truly memorable.
