Siem Sigerius is a beloved, brilliant professor of mathematics with a promising future in politics. His family -- including a loving wife, two gorgeous, intelligent stepdaughters, and a successful future son-in-law -- and carefully appointed home in the bucolic countryside complete the portrait of a comfortable, morally upright household. But there are elements of Siem's past that threaten to upend the peace and stability that he has achieved, and when he stumbles upon a deception that's painfully close to home, things begin to fall apart. A cataclysmic explosion in a fireworks factory, the advent of internet pornography, and the reappearance of a discarded, dangerous son all play a terrible role in the spectacular fragmentation of the Sigerius clan.
