I have been racing towards this book because I was so excited for Alex's story but also I had a really strong feeling about this since The Viper.  My heart raced through the whole thing.  Also, Daddy Lachlan!!! My heart.  On a minor note, the fact that Thomas is never relevant again minus a brief mention (not even by name) only reinforces my opinion that The Rock is the worst book in the series.  I LOVE this series, totally exceeded expectations.  So well researched.  I didn't expect to love it as much as I did but I'm so thankful I picked it up.  Alex and Joan are wonderful and I'm really really happy.
