In this fifth and last book of the Galactic Treasure Hunt series, the adventures of Jake, Scott, and Nojo continue, only this time Nojo is missing. Jake and Scott travel back to the lost universe all on their own to rescue Nojo. Their journey is epic and dangerous. They must battle wicked beasts and evil warlords before finding what they are seeking. Short chapters with illustrations on every page make it a great book for reading to children. The fantastic story is based on real science, so at the end of the book the author (a Boeing engineer) discusses the science. Great fun, science and adventure for children!
