I quite enjoyed the first half of this book. Cool concept and I liked the ways it got me thinking about my own life and choices. The protagonist was well developed as flawed but trying her best, which I appreciated.

The last third of the book, however, lost me.

I hated that the "perfect life" was depicted as being a wife and mother, without any other aspect of that life being given attention or meaning. I imagine the author's intent in having her leave that life was to say that life wasn't perfect, but we didn'tactually see any way she was dissatisfied with it so it didn't work for me.

The resulting ending felt trite and moralistic, and it had me rolling my eyes. YMMV, of course.
