It begins as a romance between two teenagers searching for a deeper meaning in life in their small town. When the enigmatic Anastasia shows up in the halls of Hamilton High, she changes the narrator's life, opening his mind to Baudelaire and Mozart and revealing a world of magic tricks, ghost stories, and affectionate mind games. Together the couple probe through enchanted woods, the Internet, and everything in between ... until, one winter evening, Anastasia disappears, leaving only a dress on a frozen river.
Suddenly alone, the narrator is hit with the weight of life's less playful mysteries, possible signs from the supernatural, and the mystery of what actually happened to his missing love.
