I thoroughly enjoyed this book as I did the first 2.  I felt it was very fast paced.  Halt's humor was a very nice change.  Kind of feels like the reader gets to know him a bit more.  I too had a feeling of dread for Will due to his drug addiction.  However, I did feel like the ending was a bit too quick.  But as with the other 2 books, it leaves you wanting more.  This is defiantly a winning series.
