Focus on The Family, The Christy Miller Series by Robin Jones Gunn, Books 1,2,4,5,6,7,8,9,10,11,12 missing book # 3. Books are in very good vintage condition. A little cover wear, inside pages very good. I didn't see any corner page bends, rips/tears or markings. The only thing I saw was a brown spot on 1 page in book order 7 - see last picture. Every book has a library stamp and some # written in them on one of the cover pages. The books are not new but in very good readable condition.
