'It's about a wave named Roland, it's kind of an existential children's book because I had a lot of kind of heavy questions when I was a kid that didn't get answered,' Jim told Ellen.
'It's about a wave named Roland who is afraid that one day when he hits the beach his life will be over. And when he gets deep, he's struck by the notion that he's not just a wave he's the whole big wide ocean,' Jim said of the book.
Jim said the book was written to help children understand 'that we're not just individuals, we are all part of one thing and there really is no two things, we all kind of really are the same.'
