Book 53 of 2015 is World After by Susan Ee.
Oops, I hate when I read a second book in a series by accident. Now I understand why the world isn't well explained. Still, you gotta love Angels and Demons at war. I'll keep going and read book one later.
I do like the dynamic between the female protagonist and her complicated overly macho angel love interest but it is much enhanced by the writing and mythology that backs this.
I shall go back and read the first with interest but I do not recommend you start with this one. There is obviously a void a la Jaba the Hutt's sand monster.
3 fallen angels with wing grafts out of 5.
Should I read this? Maybe after the first.
What did I learn? Angels are only human.
