Eric Fan and Terry Fan are brothers and frequent collaborators on children's books. Together, they illustrated Canadian astronaut Chris Hadfield's bestselling picture book The Darkest Dark, in which a young boy overcomes his fear of the dark. They also created the illustrations for Dashka Slater's book The Antlered Ship, the story of a curious fox and his adventure at sea.

Their first book as authors and illustrators was The Night Gardener, a critically acclaimed picture book about a boy who wakes up each morning to find that a tree in his neighbourhood has been elaborately sculpted. Their latest picture book is Ocean Meets Sky, which follows a boy named Finn as he sets sail to find the place where the ocean meets the sky. The book is on the 2018 Governor General's Literary Award shortlist for young people's literature — illustrated books.
