Annie and her mother don't see eye to eye. Her mother is all about facts and order; Annie loves art and daydreaming. When Annie finds a painting of a lighthouse, she is immediately drawn to it--and her mother wishes it would stay banished in the attic. Then Annie's mother slips into a coma following a car accident, strange things begin to happen to Annie. She finds herself falling into the painting and meeting Claire, a girl her own age living at the lighthouse. Claire's mother Maisie is the artist behind the painting, and like Annie, Claire's relationship with her mother is fraught. Annie thinks she can help them find their way back to each other, and in so doing, help mend her relationship with her own mother. But who IS Claire? Why can Annie travel through the painting? And can Annie help her mother wake up from her coma?
