This week’s Unshelved Book Club features books about a famous film director hitchhiking across America, a boy who wants to become a Hunter like his dad (and then find his dad), Dog and Bear on Halloween, cool costumes, and how to enjoy the apocalypse, plus a picture book about a super powered booger that’s a collaboration between William Joyce and his younger self, and two collections of essays, one about poetry and poets and another about living in the emotional turmoil of constant change.
