The name of this book is mysterious.

You must have your wits about you. No wandering minds allowed.

It was like walking into a treasure trove of books, hoarded by pirate librarians.

Generally speaking, books don't cause much harm. Except when you read them, that is. Then they cause all kinds of problems. Books can, for example, give you ideas. I don't know if you've ever had an idea before, but, if you have, you know how much trouble an idea can get you into.

...books were better than travel.

Despite my vanity, I fear for my sanity.

This book will not harm you unless someone throws it at you which is a possibilty never to be discounted.
