The Tunnel in Time: (To the Silly Word Place) (#1 in The Silly Word Stories)

Delia and her younger brother Jake fall through a tunnel in time and wind up in the past.

They soon realize that all the houses in their neighborhood are gone. The people living in the one house they see are aliens!
Adding to the confusion, both the kids and the aliens find themselves using weird words like derfelbocker and nogginbreath.

Will Jake and Delia be able to find their way home?!
