This 208-page full-color book includes the entire fifth year of strips (four full storylines) from October 2014 through November 2015! There's commentary! There's cast bios! There's bonus features! There's a Foreword by Diana Nock! You can also pay extra to get it doodled in and autographed, because this is America.
When this book is available on Comixology, I will put that link here.
