The world of Kildare, expatriate princess of Faerie and star of Aria, gets turned upside down when Goodfellow, the deadly, mischievous sprite immortalized in Shakespeare's A Midsummer Night's Dream, comes to New York. Convinced that Goodfellow's intentions are considerably less than pure, Kildare sifts through his trail of riddles and lies, trying to figure out just what is he up to. Her search leads to an underground soul market, where the immortal spirits of humans are bought, sold and traded ― and to the memory of Kildare's long forgotten love.
