The new series, Colton's Time Machine books, are spin-offs from the original Colton's Pocket Dragon books. Colton felt it was time for his dragons to get a little education about history, so he built a machine that would take all of them back in time. In this book Colton and his dragons will travel back in time to 1789, in Philadelphia, to ring the "Liberty Bell" with President George Washington. Then Colton and the dragons will go to 1782, in Philadelphia, to help in choosing our national symbol, "The Bald Eagle." Their final stop will be 1814, to work with Francis Scott Key to finish writing our National Anthem, "The Star-Spangled Banner."
