Newbery Medal-winning author Patricia MacLachlan has written a magical and funny tale about the joy found in using words, sharing stories, and loving a wondrous dog: Rex. Grace´s aunt is a writer. She works with words every day and teaches Grace interesting words like "melancholy" and "delirious." But Lily is often "flummoxed" by her writing. Her stories don´t go anywhere, her desk is a mess, and her writer´s group can´t help. So Lily posts an ad for an assistant: A writer of books needs an assistant, a coach, a helper, for inspiration and some magic! The next day, Grace opens the door, and there is Rex: a Labrador retriever who will change Grace´s life, and Lily´s. The word "amazing" is an everyday word for Rex, who inspires Lily, and helps Grace find the words to write her own story.
