As book imports are duty-free, Cayman has a really good selection of bookstores, each selling something different, and it is easy to spend a lot of time browsing and exploring them.
In Cayman you will find books for all ages, topics and genres. Some bookstores also carry a variety of gifts and toys.
If you're hoping to get your hands on the latest release, or you can't find a specific book, Next Chapter and Book Nook would be happy to put in a special order for you wherever possible. For second-hand literature, try The Book Loft at the Humane Society.
