I would have given a 5-star review, except for "my bad".  I am not great on geography and must admit I had some stuggle with that.  That said, I was completely engrossed.  Everything is so plausible.  The gnawing away at Ann's complacency brings her face-to-face with the world's reality.  Gut-wrenching toe-to-toe survival, whether you are the aggressor or the aggrieved, may start in a grey area--but must end in only black and white.  A really thought-provoking read.  Shamefully, religious wars or wars in the name of religion have always been and will always be.  I'll have to read it again to make sure I understand it all.  Definitely worth your time.
