You know the saying: no two people in the contacted world are more than six social connections apart. Inspired by Kate at Books Are My Favourite And Best, I apply this notion to books and challenge friends and authors to find interesting ways to hop from one book to another based on a shared author, theme, award win and so on. Today, I’m delighted to welcome Ren Hutchings, author of timeslip space opera Under Fortunate Stars, to take the Six Degrees challenge.
