Got Mystery Cults a couple of days ago, and since House Bjornaer is my favorite house, I've been expecting this books with anticipation. And I wasn't disappointed, to say the least. The focus on the Heartbeast and the ideas on the Great Beast is just perfect.
Havn't been able to read through the chapters on Merinita and Verditius yet. Trying to get my head around Criamon right now... odd stuff. 
Anyway, just wanted to throw the question out and ask what other people think of the book.
