(Mild spoilers ahead) I liked enough to read in one sitting, and the multiverse idea is captivating but... (there is always a but it seems). For an intelligent person that people around even describe as a genius, the main character acts dumb so it is a bit difficult to believe the story. Also, there are some flaws in the logical flow that again give a feeling of disbelief. For this reason, the book seems more like a thought experiment to explain the implications of a multiverse based on the branching idea (every decision can be a splitting point to multiple realities and the love of the main character becomes then a converging point). Either way, it is a worthwhile reading, is a standalone book (an extra star for this) and it makes you feel as much as it makes you think.
