J. K. Rowling "Harry Potter and the Half-Blood Prince", 2005, stated 1st American edition, first state with full numbering sequence, better yet - error copy! - ending on page 652 instead of 672. Very rare.

It has two notable errors; one is that it’s only 652 pages instead of 672. The other is that on page 100 (not page 99 like usual) it reads “and when you’ve got your eleven (should be ten) ‘outstanding’ O.W.L.s…” which was corrected in later printing.

This is a rare and highly sought-after first edition hardcover copy of "Harry Potter and the Half-Blood Prince" by J.K. Rowling. This book is a must-have for any fan of the Harry Potter series. It features an engaging storyline that takes readers on a magical journey to Hogwarts School of Witchcraft and Wizardry.
