Award Winning Teaching Book
Format: Hardcover
This story has a lovely story that is a great teaching moment for young children. I enjoyed the illustrations and I find these stories about real life situations of other people in other circumstances other than your own offer great teaching moments for the young readers....Recommend you read it to your young children and it gives you a good opportunity to explain to your children that even those who have much less than you do....but, have love and family are wealthy in their own way....and to express all types of families exist and are all just as important and your individual family is to you. Important that they are getting more books out that offer important lessons about life to young people...to grow their empathy for others...and caring feelings for others from a young age. Recommend

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.
