I bought this book as a second hand book, and it's pretty damage but you can read it.

lengli_chong (Singapore) (2018/08/31): My copy is in good condition, my son had read it a few times, so except for slight dog ears on the cover and slightly yellowed pages, the condition of pages and spine are good. General condition 9/10.
My 10 year old son love the story, even though he thought it was pretty grim and scary. I actually asked him is it too much for him seeing as how it was actually meant for young adults (teens) but he assured me that the story is gripping and he want to read more from the series.
