Alex Malarkey is best known for co-writing the book "The Boy Who Came Back From Heaven." The book was a supposed autobiography about the time he was in a coma following a car accident.

The book was written by Alex and his father, Kevin Malarkey, in 2010. It told a story of when Alex was in a coma in 2004 at just six years old.

The book was later removed from shelves after Alex admitted to lying about going to heaven for attention.
