I'm not exactly sure if this is what you're asking for, but I highly recommend anything by Max Lucado--especially for new believers. He has a way of communicating in simple, common language and everyday examples that make him easy to understand, but still very profound. I've bought and read just about every book he has on the market, and I have yet to be disappointed. And everyone I've lent my copies to has enjoyed them as well.
John Ortberg is very good, too. He tends to be a little more humorous in his writing, which keeps you from feeling 'weighed down'. My wife just finished reading If You Want To Walk On Water, You Have To Step Out Of The Boat. She loved it!
