Ugh.  I guess in every series I read there's one book that is just bad.  I thought it was going to be the Arrow, but actually it was the Rock.  I didn't really like either MC.  Elizabeth especially is so annoying.  She's actually insufferable compared to all the other amazing women in the series.  Thomas is okay.  Honestly I don't know what the point of a new guard so close to the end of the series is, especially one with such a dumb specialty in comparison to the rest of the guards.  Also wild that he can't even ride a horse but somehow gets added to the guard???  I'm going to let it go because I really do love this series as a whole, but this book is easily the worst one in the series.
