Book 3 delivered a realization to me about why I love this series so much.  The characters continue across the series and they grow.  They don’t keep making the same mistakes.  Each book is complete in itself, but as the series continues, it forms a well-rounded world with realistic characters.  I’m at the point where I expect to meet the characters in real life. 

THRALL is another excellent installment.  If you’ve read the first books, don’t miss out on this one.
