In the wrong hands, some books can be dangerous-and some libraries can be positively deadly. Marco, a young tabby, has been perfectly happy as a small town library cat and newly appointed Guardian of an ancient mystical book. However, when otherworldly creatures begin roaming the stacks after hours, and his mentor, the elder Guardian, is killed, Marco's incent world is shattered. The young tabby cat is on his own, ill-prepared for the daunting task of safekeeping the magical book of power-and the very heart and soul of the library. Time and space are barriers for Marco's shape shifting friends and enemies as he learns that the library is the most dangerous place worth saving. Guardian Cats is the classic hero's journey with cats as the guardians of an ancient mystical book of power.
