Simon and Auden Triller are twins whose only similarity is the surname they share. From an early age, Simon's life is filled with academic and athletic accomplishments, friends and adults who admire him. As he grows older, his determination to succeed and passion for life are matched only by his unshakable devotion toward his brother, who is unappreciative to the point of contempt.

Auden's life, on the other hand, is as sparse as Simon's is full. Wanting nothing more than to live on his own unambitious terms, in a world free of comparisons to his twin, he can't seem to manage the smallest demands without having them turn into desperate predicaments requiring his brother's help.

Satirical, self-eviscerating and world-weary, Auden's voice guides the reader back and forth in time and place. Gradually and painfully, Auden realizes the solitude he's chosen for himself is less peaceful than insanity-making. When, finally, he loses his grip on reality, his actions precipitate a tragedy that threatens to permanently sever his fraternal bond, just when he needs Simon most.
