Frequently Asked Questions

Where can I get my book delivered to?

We deliver to most countries worldwide. Enter your delivery address during checkout and we'll display the shipping cost when we know where to send your book.

How do supporter names work?

Every person who pledges to help to make a book gets their name included in a supporter section as a thank you as long as they pledge before the list closing deadline. If you want to add a different name, this can be changed in your account after you have completed your pledge.

Will the book and rewards that I receive look the same as the images shown on the Unbound website?

Book designs, cover and other images are for illustrative purposes and may differ from final design.
