The Invincible Little Lady: Volume 6

Despite uncovering the truth of a long-forgotten legend and exploring a distant ancient ruin, Mary still hasn’t found a topic for her research project! However, she was left with one lead to pursue—according to her archeologist acquaintance, an ancient elven town known as Kairomea may have a solution. The town is said to be a repository for all manner of primeval knowledge, for its inhabitants maintain a massive library known as the Grand Archival Tower, where they study and preserve a trove of aged documents; surely, Mary believes, she could find magic to suppress her powers there, of all places! But the depths of the world’s knowledge aren’t the only mystery in Kairomea, and Mary and her friends aren’t the only ones seeking answers to questions that can alter life as they know it... Can Mary piece together the truth behind the town’s enigmas before its dormant magic falls into the wrong hands? Or will her academic career (and the library town itself) meet an untimely end?
