Emmett Farmer is working in the fields when a letter arrives summoning him to begin an apprenticeship. He will work for a Bookbinder, a vocation that arouses fear, superstition and prejudice — but one neither he nor his parents can afford to refuse. He will learn to hand-craft beautiful volumes, and within each he will capture something unique and extraordinary : a memory. If there's something you want to forget, he can help.
If there's something you need to erase, he can assist. Your past will be stored safely in a book and you will never remember your secret, however terrible. In a vault under his mentor's workshop, row upon row of books — and memories — are meticulously stored and recorded. Then one day Emmett makes an astonishing discovery : one of them has his name on it.
