As usual, gorgeously written and engaging, though also a little exhausting as the protagonist lives out various (sometimes quite short) possible futures and dies repeatedly. I admit to feeling somewhat at a loss at the end of the book. In a way, it's a meditation on the points in one's life which offer different paths, as well as the different ways history could turn out if different paths were taken, and also on the author's capacity to choose different paths for characters. Beyond that, I couldn't really say what it's about, though it was peculiarly addictive seeing how the latest version of the protagonist's life would work out. (Quite often, very wretchedly.)
