Stefan Bachmann is the author of the internationally bestselling novel The Peculiar and its acclaimed sequel, The Whatnot. He was born in Colorado, spent most of his childhood in Switzerland, and is now studying modern music at the Zurich University of the Arts. When he's not writing, he can be found traveling to someplace chilly, or holed up beneath his college in the dimly lit labyrinth of practice rooms, which may have inspired the subterranean scenes in A Drop of Night. That . . . and the Paris catacombs, a weird dream about a golden corridor, and a general interest in history.
