Another great Vonnegut novel! Not my favorite of his but still so thought-provoking and optimistically nihilistic. With the witty dark humor Vonnegut always has. 
Themes and topics are anti-war, morality and the gray area/complexity of right vs wrong, ethics, life’s purpose, and love. 
I liked that it was written from the perspective of Campbell in jail. Also had some twists & turns that I enjoyed. 
Makes me reflect on ethics, morality, and how right vs wrong is not simple.
