Hello Leona (
@Leona_firefly), first off,
WELCOME TO CF
As far book recommendations go, here are a couple. First, an autobiography that, if it was fiction and hadn't really happened, would be a nearly impossible story to believe. Make sure to start reading it early in the day because you may not be able to put it down. I couldn't, and neither could my pastor when he read it

You will laugh, you will cry, and you will be utterly amazed!! My favorite chapter is called "Jesus, the Motilone".

The Screwtape Letters by C.S. Lewis - a Christian Classic and a GREAT read as well. It's fictional, but it will help you understand what Satan's demons are up to in your life, as well as help you to recognize their "flaming arrows" for what they really are far more quickly.
It's actually a collection of short stories by Lewis that he wrote from the demons POV, which means that when you see the word "Enemy" in this book, for instance, it's referring to God (as the stories are mostly a dialogue between two demons, Uncle Screwtape and his nephew, Wormwood).
BTW, the stories were first read on the air (on radio) in the 1940's by Lewis himself.
God bless you!! (
