New York Times best-selling author-illustrator Oliver Jeffers and fine artist Sam Winston deliver a lyrical picture book inspiring readers of all ages to create, to question, to explore, and to imagine. A little girl sails her raft across a sea of words, arriving at the house of a small boy and calling him away on an adventure. Through forests of fairy tales and across mountains of make-believe, the two travel together on a fantastical journey that unlocks the boy s imagination.
