Author Andrew Shaffer joins Sheena and Derek to discuss the tie-in book to this year's Ghostbusters release, Ghosts from Our Past. The book - written from the viewpoint of Erin and Abby - is an integral part of the film's plot and, thus, a huge point of discussion. Andrew talks about what he pulled from to craft the book, what he loves about Ghostbusters in general and what made the recent film a worthy part of the franchise.
