What stalks among us
(Book)

Sadie and Logan make their first mistake when they ditch the end-of-year senior field trip to the amusement park in favor of exploring the Indiana back roads. When they come across a giant, abandoned corn maze, the corn is the vibrant green of midsummer. It's the wrong season: corn mazes are for the fall. Second mistake: they enter anyway-- and stumble on corpses in the maze. Corpses identical to them in every way, from clothes and hair down to a missing tooth. Who-- or what-- is hunting them? And will they be able to get out alive? -- adapted from jacket
