"Sally" is a post Ice Age cave dweller, William is a 22nd century particle engineer who travels from world to world in a modified Winnebago. Together, this unlikely duo set off to find the world farthest from the center of the Macroverse (which contains every possible Universe). Aided by William's hyperdimensional computer, Bob, and accompanied by Sally's pet Tiger, they pass through many worlds, some truly bizarre and some not-too-different from their home worlds. "It's fun, and I enjoyed it." -Piers Anthony hipiers.com Newsletter Apull 2011
