I recently read Pigs in the Parlor by Frank and Ida Mae Hammond.  If you want to know the fundamentals about deliverance, I highly recommend this book.

Once you get a handle on the basics, there are a few more books that will help you on the topic of deliverance:  Prayers that Rout Demons and Break Curses,  Unshakable, and Fasting for Breakthrough and Deliverance are all books I personally own and recommend written by Apostle John Eckhardt.

Tests and Trials

If you are going through testing and trials, I highly recommend The Masterpiece of the Wilderness by Deanna Deering.  During some of my hardest trials, I read this book and was greatly impacted by what I received.
