I've read two books recently that I want to recommend. These are probably the most powerful books on relationships I've ever read (granted, I haven't read many, but these books were still tremendously powerful).
If you are looking for authentic, highly practical, and radical books on Christian relationships -- or really, if you're looking for books on Christian relationships at all -- these are for you: When Dreams Come True and When God Writes Your Love Story, both by Eric and Leslie Ludy. (Eric Ludy is the same author of another book I reviewed recently, The Bravehearted Gospel.)
When Dreams Come True is the inspiring, entirely true love story of Eric and Leslie Ludy. This book is a gripping read; it is written like a novel, and I found it impossible to put down. It chronicles a beautiful, emotional love story that "only God could write"; one that flies in the face of modern Hollywood's twisted misconceptions on romance. This book is an amazing example of how God can write a love story infinitely better than any fictional book or movie we could ever slap together. If you want to witness a moving, eye-opening romance that defies our culture, then read When Dreams Come True.
When God Writes Your Love Story is a perfect companion to When Dreams Come True. In it, the authors dive much deeper into the themes touched in When Dreams Come True. It is filled to the brim with challenging, thought-provoking, and practical advise, applicable regardless of your age, or if you're years away from entering a serious relationship. All in all, I highly recommend it; read it, and then let your friends read it.
