In an alternate universe, all babies are born with a level of empathic sensitivity to others; an ability to sense emotions, to glimpse deep into a person's soul with just a kiss. Except Kurt Hummel. Registering at a mere 0.5 on the Hawkins Scale of Empathic Sensitivity, Kurt has resigned himself to a lonely life, empty of touch or true love. That is, until the mysterious Blaine Anderson transfers to McKinley, and everything Kurt thought he knew was changed. But finding love is never easy, even in a world where everyone’s emotions are shared. This is the story of the boy who could not feel, and the boy who felt too much.
