The are here, everywhere.
In various lockers, drawers, even bags, on tables, beds and even floor.
We might only buy 1 book every 6 months as we visit the library at least once a week. Loads of books go in and out. We swap books with friends. We give books away. We even have an electronic book.
Books are big friends on board and we love them - even if they are really bad for the water line!
