You are on a flight from New York to London when an alien space ship abducts you from your plane. Aboard UFO 54-40, you meet the UT-Y, an alien race searching the galaxy for the utopian planet of Ultima. Among the other abducted members on UFO 54-40 are humans captured from different eras and aliens from across the galaxies. Will you continue on the search to find the utopian Ultima?

A story of galactic exploration and daring adventure leads you to make choices about which planet you’ll call home and if you’ll ever return to the life you’ve always known. For kids with a love of swashbuckling space adventure, this is an imaginative and satisfying page-turner.
