Query: Cannot keep it on my bookshelf

As a teacher of reluctant readers, I cannot keep copies of this book on my shelves. I used to introduce Stanislaw Lem to the students first, but this intimidated them. After I changed to letting the stories hook them first, I have found all of his books disappearing. They are fascinated by irreverence and humour in quality writing. I cannot complain about the books disappearing; they are reading.
