Those reading this thread may like http://www.inspiredreads.com/subscribe/ , "Inspired Reads is all about finding and sharing Christian Kindle Books on a Budget!" I came across Inspired Threads through Pixels of Ink (free Kindle books of many types) today.
Read a very nice Christian romance, Stuck in the Middle, http://www.amazon.com/Stuck-Middle-Sister-- -Sister-eboo... It's currently free for Kindle. Totally clean, would feel comfortable having a teen or even middle school age girl read this one. The book/relationship is about choosing what God wants for your life.
