Galaxy Walkers 2: Unity of Worlds

By Kris Paulsen

"Paulsen has created a highly enjoyable blend of science and fantasy that I recommend to young and young-at-heart readers who like speculative worlds governed by unique physics. Very highly recommended."

-Asher Syed from Readers' Favorite

When thirteen-year-olds Lyra and Archie test a new invention, everything goes wrong. Janus tricks them, sending them and their nemesis Saros into a wormhole into another universe, where they crash-land on a strange planet.

Far from home, Lyra and Archie meet Xandros, a young dragon who rescues them from danger.

To return to their universe and save Xandros's sick father, they must find the Guardian of Time and complete five trials. Meanwhile, Janus is causing chaos in their universe, and time is running out.

Can Lyra, Archie, and Xandros trust Saros long enough to survive the trials and save both worlds, or will her hunger for power destroy everything they are fighting for?
