As the Voyagers continue their world-saving mission, the stakes keep rising, from a malfunctioning ship (Escape) to an evil-alien-clone takeover (Seventh). The preteens, though, are most resourceful when pushed to their limits, and they won't give up until their quest is complete. This appealing multiplatform collaborative series wraps up satisfyingly with teamwork proving to be the crux of the intergalactic adventures.
