This is a post apocolyptic book from 1987 by Robert McCammon. It’s a very long book at nearly 1000 pages, I think it’s heavily influenced by The Stand by Stephen King which was released a few years before.
The particular apocolypse in this story is nuclear war between the US and Russia, over the first few chapters missles start flying overhead and destroying the world of the characters we have been introduced to.
The story is told from multiple viewpoints, but the main plot is around a girl named Swan who has the power to make living things grow with her touch. In the final section of the
The story is clearly Christian, there is a character which is obviously satan, and Swan is a standin for Jesus. The town that the settle in near the end of the book is Mary’s rest, and several characters develop hard helmet like growths on their heads they call Job’s mask.
Some of the sections of the book, particular the plot of the antangnonists is really quite brutal. There is a fair amount of sadism on show, but I thought that it was well done. The structure and pacing of the book I thought was great, initially I was daunted about reading such a long book for book club, but I finished it with plenty of time left.
