Whoa whoa whoa, let's pick books for which 80% of the western world hasn't seen the movie version. Let's try and skip the standard school material too. Well I'm guess that leaves very little. Not copy righted, no movie version, not taught in schools, and we can get an e-version.
Now, if these are taught comprehension tests. Like "What was beside the cat when Peter enter the kitchen, on his first Sunday at the estate?" And it's not a bloody knife. Meaning not a key, or pivotal plot element. Just the kind of thing you remember about a book you read in school 20 years ago.
Sorry, for interjecting. But people will be all over the tests for just those reasons. Too easy. Eveybody already knows that story. bla bla bla.
