This engrossing tale of angels and demons is a very fun read. I stayed up far too late last night reading it, and I regret nothing!
I found the author's take on Heaven and the creatures within to be fascinating. The characters come alive, with human foibles and errors. The most amazing thing to me was how the creatures that had no voices-- horses and a grackle!-- were absolutely 'people,' with personalities and agency. I loved them, and was almost more interested in them than in the "people." Almost. Also, each character had an emotional arc, and were heartwarming or horrifying in their turn, but definitely sucked me in and had me dying to know what was going to happen. Thus the late night!)
Also, this is not a religious tract. There is no "bible thumping" or preaching, this is pure fiction. Fiction with many Bible references, which if you know your Bible, you may enjoy. I did. But it's definitely not a serious religious theology tale-- and if you're worried about the "Christian" overtones, I would definitely say don't.
The only things that kept this from being five stars were the occasional dip into what felt like forced melodrama, and the ending, which felt... off, somehow. Perhaps too long? It wrapped things up very nicely, and I was grateful for the denouement, but I found myself frowning at it anyway. I am sorry that I can't put a finger on exactly what bothered me, other than to say it is entirely possible it's just me.
Still, this was a very fun read, and if you like angels and demons and Revelations and the like, give it a try!
