When the mythical Key to the Universe lands in 107-yr-old Abe's antique shop on the Martian moon of Phobos, he and his great-grandson Quinn know the Key is something very special

As word starts to spread, Martian Mafia, the Solar Government, and rival antique dealers will go to any lengths to get their hands on an artifact that can potentially unlock the very meaning of existence.

From the desert world of a long-dead intergalactic philosopher to a techno planet whose atmosphere is composed entirely of satellites, Abe and Quinn are about to see more of the universe than they ever expected as they race to discover the secrets of the Key.

They might even survive the trip.
