I recommend this book – Fervent by Priscilla Shrier.

This book is ???
During this prayer & fasting season, I have dedicated myself to reading a number of books that boost my spirit man (remember, this is a year of reading!!!). I encourage my women folk who desire to remain fervent in spirit to get it if you can, and the men folk who love us should get it for the ladies in their lives. This books is awesome and will change you from the inside out!
