I try to grade the books as fairly as possible, but one person's small tear is another's gaping chasm. I may simply have missed something. So, if you are dissatisfied with the description of any item, please contact me in the first instance (info@starlingbooks.co.uk) and we'll sort something out. All dust-wrappers are supplied in a removable protective cover. And if it doesn't say it is a First Edition, it isn't.
