Will have to come back later to finish, but a couple of thoughts: 
 I liked it. Not as much as book 1, but I still enjoyed it. I missed seeing more of Akeldama (the scene at the end of Soulless was one of my favorite parts and I love the interaction between Alexia and Akeldama) 
 Finally more steampunk elements in this one. 
 Lots of tongue in cheek banter. 
 Bit of a cliffhanger ending, so I'm glad I don't have to wait long for book 3.
