This sequel was quite exciting - though I think I enjoyed _The Descent_ more. But I did read that these books are slated to be a trilogy which is VERY exciting. This one held a few surprises and overall, I thoroughly enjoyed it - even if it was a bit open ended for my tastes. I just mean that it was a little unsatisfying in the end with many questions as to what direction the ending will take... but hopefully the third installment of this trilogy won't take another ten years!
