Wyatt is fifteen, and nobody in his homophobic small town of Lincolnville, Oregon, knows that he's gay. Not even his best friend (and accidental girlfriend) Mackenzie.Then he discovers a secret from actual history: Abraham Lincoln was in love with another guy! Since everyone loves Lincoln, Wyatt's sure that if the world knew about it, they would treat gay people differently and it would solve everything about his life. So Wyatt outs Lincoln online, triggering a media firestorm and conservative backlash that threaten to destroy everything he cares about.Now Wyatt has to pretend more than ever that he's straight (because no one will believe a gay kid saying Lincoln was gay). Only then he meets Martin, who is openly gay and who just might be the guy Wyatt's been hoping to find. Will Wyatt stay closeted to change the world, or will he let Abraham Lincoln's gay romance fade back into history and take his own chance at love?This nineteenth- and twenty-first-century coming-of-age, coming out story was inspired by real historical evidence that Abraham Lincoln was in love-romantic love-with another man. QUEER AS A FIVE-DOLLAR BILL asks LGBTQ teens (and everyone else), What if you knew a secret from history that could change the world?
