LeUyen Pham and Shannon Hale are the team behind the bestselling picture books Itty-Bitty Kitty-Corn and Pretty Perfect Kitty-Corn, the bestselling graphic novels Real Friends, Best Friends, and Friends Forever, and, with Dean Hale, the early chapter book series the Princess in Black. They've made a bunch of other books, too. They are both: moms of kids who love parties, wives to husbands who give them homemade cards, honor award winners (Caldecott and Newbery), caretakers of cats, and believers in unicorns. Pham lives in Los Angeles, Hale lives in Utah, and although they also have friends close to home, their best friend hearts are always entwined.
