The Evolutionary Mishap

From publisher blurb: When an explosion in a nearby section of the laboratory sends you and several other animal test subjects through an interdimensional wormhole, you suddenly find yourselves transformed into highly trained humanoids capable of speech and complex thought. You and your fellow lab animals now find yourselves in an alternate version of feudal Japan and in the middle of war. Even worse, your existence in this alternate dimension seems temporary and your very lives depend on returning to the world from whence you came—but how?
