The Essence of the Thing

The brilliant mathematician Lisa makes a living by cleaning. She doesn’t quite understand the motives and actions of people, but the things that have lived with people tell Lisa everything about their owners. Even things she would rather not know.
This book can be read in different ways: as a detective story, as a coming-of-age novel, as a philosophical parable, even as a discussion on the unity and opposition of music and mathematics. But however you read it, fragile yet stubborn and fearless Lisa will forever hold a place in your heart.
