Full review is up on my blog: http://books-underblankets.blogspot.ie/2015/01/review-tk-sbems.html

The Key is the final incredible installment in the trilogy. We follow Ida, now trapped in the Borderlands, and the remaining members of the Circle left in the town of Engelsfors as they overcome new challenges and difficulties in their final battle.
