A disgraced TV presenter's plan to end it all is thwarted by the arrival of a stranger with the same plan, and then another, and yet another. The mood is spoiled (suicide being by & large a lonely affair) so they take, mostly unwillingly, the long hard way back to their lives.
The only thing I find unlikely in the story is that initial meeting (but that's why it's called fiction). The rest: the fact that once together they don't jump, they keep in touch even if tortorous, the state of their own lives, etc., does not require a leap of faith.
I enjoyed reading the book, even if I didn't find all the characters likeable (that girl just drove me up the wall). It's fresh & thought-provoking; and despite the seemingly heavy topic, it's perfect for holidays.
