Our zany hero, Two-Headed Chicken, has traveled the multiverse using the AstroCap and romped through the chronoverse using the TimeCap. Now they dare to ask: What happens if they use both caps at the same time? Answer: Chaos! Unfortunately, the chaos is so ridiculous that the reader slams their book closed, trapping the double-noggined main character in eternal darkness. But wait! Two-Headed Chicken escapes into the Cosmic Library, which contains every book ever written. Now, still pursued by the chicken-hungry moose Kernel Antlers, Two-Headed Chicken hops their way through a parade of familiar titles, from a hundred-acre wood to a kissy vampire novel, interacting with the befuddled characters and leaving mayhem in their wake. With interactive puzzles and activities and wall-to-wall jokes, Tom Angleberger delivers another absurdist delight in this madcap series.
