Agent Boo Vol. 1: The Littlest Agent

In a reality where countless parallel worlds lie just out of sight, the Agents work to keep them hidden from humanity. The first volume introduces Boo, a fourth-grader and the smallest agent ever, whose size makes her easy to underestimate. When the rest of the team leaves Space City to battle Queen Misery's Commissars on another world, Boo is left behind to defend her home world alone, armed only with her training and a loyal feline companion, and must outwit the devious enemies threatening it.
