2 1/2, rounded to 3. This is kind of a “Choose your own adventure” with a couple who have made a pact to commit suicide when they both turn 80. The pact was made because of Kay's father's decline into Alzheimer’s. The book then goes down several rabbit holes, posing different endings, depending on what Kay and Cyril choose to do.
I can’t say that this was a terrific read for me. It was, at times, bitter and depressing, and then sort of upbeat (but not really). I’m sort of surprised I stuck with it, however, the different endings kept me sort of engaged.
