Trade Paperback. Condition: Good. Good, ex-library paperback with associated ex-library flaws, minor soiling to beige wraps, and two leaves that have been awkwardly cut and bound so that they are shorter on fore-edge and extend slightly beyond text block on bottom edge (text is not affected); stapled binding. Text is unmarked.
