Frank Schmeißer lives in Cologne, Germany and is the author of several children’s books in German. Superheroes is his first book published in English. Schmeißer enjoys reading printed books rather than digital ones, although ever since several of his books sunk while he read them in the bathtub, he would rather listen to audio books there. If he had a superpower, he would want it to be endless patience.
