This is a fun "book-about-books", espcially if you're well aquainted with the British masters such as Shakespeare, Dickens, Wordsworth and, well, the Bronte sisters. The premise of people being able to interact with characters from literature is facinating. The zany alternate universe where time-travelling occurs and the Crimean war still rages is a bit over the top; however, it is literary science fiction after all.
My two favorite aspects of the book were the delightfully munching bookworms that can alter literature and the notion of French Revisionists always trying to undermine British historical triumphs.
The protagonist, Thursday Next, is likable enough. She is a Special Operative in literary detection and fights against the delicious villain Acheron Hades, whose idea of power is to wreck havoc in famous literature.
Of course, the book is quite silly with minimal character depth and run-of-the-mill writing; however, the imagination of it all makes it all worth it. It is simply a fun read!
