4.5 stars. This one shows off Hambly's world building skills nicely, and it is a joy to read about the relationships amongst the main characters. In a reversal from more stereotypical gender roles, when John and Jenny are apart, John is often wishing Jenny was there to solve this or that problem, better implement this or that plan, and he ends up having to do things the hard way. On the other hand, Jenny just misses John, and doesn't particularly miss/need John's skill set. This is probably just my reading style, but when the plot gets propulsive (which is often), I very easily get caught up and enjoy the ride, but also find myself not understanding several details.
In Book 1 especially, we hear a lot about Jenny caught between kids/husband/home and work/magic. I thought that was really well done. In Book 2 and the start here, we hear a lot about how the victims of possession still guiltily yearn for their demon, and all of the emotional fallout from that. The volume of ink Hambly spills about this makes me think she is talking about some real world psychological issue (much like issues facing working women in the 80s), but I can't figure out what it would be. It doesn't line up with survivors of abuse, nor addiction/substance abuse, though it has elements of both. If there is a point in there, I missed it. But beyond that, I just was not looking forward to more yearning for pain/sadism/deprivation, and the beginning made me worry that we would be wallowing in that for a while. Thankfully, the book/characters move forward in short order.
