Ordering Open Up
If you’re in Ireland or Britain, and you’re in the position to buy the book from a local independent bookstore, that would be amazing. Otherwise, you can order physical copies or an eBook version from all the usual places. Or if money’s tight, please ask your library to order it in!
Other places I recommend:
UK
Ireland
Books Upstairs (postage is only €3!)
Everywhere else
You can try asking your local bookstore to order it in; or alternatively try Wordery (who offer free and/or very low postage costs)
