Oren Lavie has green eyes, long curly hair, and relatively cold feet. He was born in June, one week behind schedule, and has been trying to catch up ever since. He likes to sleep late but does his best writing early in the morning, which is why his best writing so rarely gets done. Oren is a musician, director, and author of children's books. His debut album, The Opposite Side of the Sea, was released worldwide to critical acclaim, winning him the prestigious ASCAP Foundation Sammy Cahn Award for his lyrics. The music video for "Her Morning Elegance" was nominated for a Grammy Award and became a YouTube hit. Oren wrote "A Dance 'Round the Memory Tree" for The Chronicles of Narnia: Prince Caspian movie. The Bear Who Wasn't There is his first book to be published in the US.
