I don't usually read humour books, but I really enjoyed this. And even LOL'd a number of times. It's lighthearted... for the most part. But seeing as the major theme is grief (and how to deal with it), the eye-watering moments are inescapable. It's rather predictable, but not in a terrible way, which helps keep it lighthearted (and heartwarming) and makes it a gratifying read. The Crisis could have been more dire, so maybe closer to a 3.5, but rounding up.
