A lonely girl draws a magic door on her bedroom wall and through it escapes into a world where wonder, adventure, and danger abound. Red marker in hand, she creates a boat, a balloon, and a flying carpet that carry her on a spectacular journey toward an uncertain destiny. When she is captured by a sinister emperor, only an act of tremendous courage and kindness can set her free. Can it also lead her home and to her heart’s desire? With supple line, luminous color, and nimble flights of fancy, author-illustrator Aaron Becker launches an ordinary child on an extraordinary journey to her greatest adventure of all!
