Lot of 6 books from best selling author Allen Drury.    Titles are:  The Promise of Joy, A Shade of Difference, The Throne of Saturn, Come Nineveh, Come Tyre, Mark Coffin U.S.S and The Roads of the Earth.  These are used books in varied condition but all good reading copies.  First two listed are hardcovers, rest are paperback.  Good luck!!
