After an all night adventure, Quentin's life-long crush, Margo, disappears, leaving behind clues that Quentin and his friends follow on the journey of a lifetime.

Quentin Jacobsen: She loved mysteries so much, that she became one.
Quentin Jacobsen: What a treacherous thing to believe that a person is more than a person.
Margo: All the paper kids drinking beer some bum bought for them at the paper convenience store. Everyone demented with the mania of owning things. All the things paper-thin and paper-frail. And all the people, too. I've lived here for eighteen years and I have never once in my life come across anyone who cares about anything that matters.
Ben: [Hears a noise] Bro, can we go?
Quentin Jacobsen: What if it's Margo?
Ben: What if it is literally anything else?
Quentin Jacobsen: Interesting capitalization.
Margo: Yeah. I'm a big believer in random capitalization. The rules of capitalization are so unfair to words in the middle.
Margo: It's a shame, don't you think? All the strings inside him broke.
Margo: Everything's uglier up close.
Quentin Jacobsen: Not you.
Quentin Jacobsen: Margo always loved mysteries. And in everything that came afterward, I could never stop thinking that maybe she loved mysteries so much that she became one.
Quentin Jacobsen: And for Margo? I heard someone say she was in the resurrection of a play on Broadway. I heard another person say She was giving surfing lessons off the coast of the Bahamas. But I stopped listening to those stories. Because whatever Margo is doing, wherever she is now, I'm sure it's something special. But hey... That's her story to tell.
