Julian Donahue is in love with his iPod.
Each song that shuffles through 'that greatest of all human inventions' triggers a memory. There are songs for the girls from when he was single; there's the one for the day he met his wife-to-be, and another for the day his son was born. But when his family falls apart, even music loses its hold on him, and he has nothing.
Until one snowy night in Brooklyn, when his life's soundtrack-and life itself-starts to play again. He stumbles into a bar and sees Cait O'Dwyer, a flame-haired Irish rock singer, performing with her band, and a strange and unlikely love affair is ignited.
Over the next few months, Julian and Cait's passion for music and each other is played out, though they never meet. In cryptic emails, text messages, cell-phone videos, and lyrics posted on Cait's website, they find something in their bizarre friendship that they cannot find anywhere else. Cait's star is on the rise, and Julian gently guides her along her path to fame-but always from a distance-and she responds to the one voice who understands her, more than a fan but still less than a lover.
As their feelings grow more feverish, keeping a safe distance becomes impossible. What follows is a love story and a uniquely heartbreaking dark comedy about obsession and loss.
