Margaret Atwood discusses MaddAddam, the last instalment in her speculative fiction trilogy.
MaddAddam is a three part book series, or better described as a "simultaneoul", as Atwood coined it in the interview:
Oryx and Crake (MaddAddam, #1)
The Year of the Flood (MaddAddam, #2)
MaddAddam (MaddAddam, #3)
This is a great interview if you are interested in the "simultaneoul"!
