I love Gena Showalter and I read the Lords of the underworld series first.  This series is just as addicting.  I like how all the books intertwine and build off of each other, and even more I love how each book shows different sides of the same battle.  In one book the dragons are our heros, the next they are the enemy.  We see things like that throughout.  Its a great example of there are different sides to every story.
