New installment of the SundanceTV hit is based on 'The Two-Bear Mambo,' the third in Joe R. Lansdale's book series.

"First and foremost, the series is about the emotional impact this terrible tragedy had. I couldn't be more thrilled to have such incredibly talented people committed to bringing our lead characters to life," Robert C. Cooper, the show's creator and executive producer, said in a statement.

The program is based on the non-fiction books Bad Blood by Vic Parsons and The Gift of Death by Andre Picard, as well as on Cooper's first-hand experience having contracted Hepatitis C from tainted blood.
