Books 1 through 12 of the Sierra Jensen Series missing only Books 2 and 6. Books 1, 3, 4 look great. Books 5 through 12 are former library books with stickers on spine (see pictures) and the title page on each has a couple of squares cut out of them (see pictures) There is a cut place at the top of page 21 in book 7 but doesn't affect readability.
