Finding meaning in sadness, defining the different types of love and looking at the complexities of masculinity, are the overarching themes in Trent Dalton's novel, Boy Swallows Universe. Trent shares with host Angela Ledgerwood how he used this book to put a positive spin on some of the sadness of his past and how he used his character, Eli, to explore what a do-over on his life would have looked like.
