MacKenzie Cadenhead was born and raised in New York City, where she mastered her driver's ed lessons in Chinatown, but somehow never learned to ride a bike. After trying her hand at a number of odd jobs—holiday gift wrapper, tour guide, pizza delivery person, waitress at IHOP—she spat in the face of employability by delivering the one-two punch of a BA in English (Haverford College) and a Masters in Dramaturgy (Brooklyn College). Thanks to a case of mistaken identity (or to her interviewer being too embarrassed to admit that he didn't know what a dramaturg was), she was hired as a comic book editor for Marvel Comics. At Marvel she developed new content for young and teen readers, including the all-ages Marvel Adventures line, Spider-Man Loves Mary Jane, Spellbinders, and Runaways, an ALA Top Ten Best Books for Young Adults, 2006.

These days she writes children's books and reads them to her family, most notably her dog, Smudge. Her middle-grade novel, Sally's Bones, is currently available wherever books are sold. Her Young Adult novel, Sleeper, will be released in August 2017.
