Mirror's Fathom is the story of Tycho Wilhelm Lund anarchist, pirate, and thief of a legendary mirror. Tycho is also a great-nephew of the Danish philosopher S ren Kierkegaard and is, when the novel begins, a mild-mannered antiques dealer who is asked to assess the value of some furniture at the home of Regine Schlegel, Kierkegaard's famously jilted former love. Upon his arrival, Tycho who has no interest in philosophy finds himself at a meeting of the Kierkegaard Circle, a group faithfully reading aloud Kierkegaard's works. There he meets, and falls for, Countess Juliana Sophie, herself a passionate follower of Kierkegaard's thinking and self-appointed mistress of the "School for Selves."
