DNF @ 25%

The idea of this book is brilliant - being able to flit in and out of different paths your life could have taken, if only you had made different choices ... but it did not pan out for me. I normally don't really mind not having good explanations for fantastical elements (see: the movie About Time), but here it didn't work. The characters held appeal and I was interested in seeing what happened to them, but ultimately the plot held me back and I struggled to get to 25%.
