Amazing book, very bad shipping.
Format: Paperback, Format: Paperback
This is a wonderful series and I am very happy to finally have a copy. Art and story are phenomenal especially if you like steampunk and fantasy. Even more so if you enjoy eldritch fantasy. That said I bought mine new and it arrived on time.....but looks like the book was sadly damaged from poor packing and very rough transport. Thankfully none of the pages besides the front few were torn. The bent and warped pages might need some saving. The amount of damage does not make it look new, despite purchasing a new copy. The box looked damaged when it arrived as well. With signs of one side being dented like it was tossed. So recommend the book, but watch out for the shipping.
