I'm having trouble finding "Jane Eyre"?

Jane Eyre was originally written by Charlotte Brontë and published in 1847. You're not going to find an original edition, so you'll find a reprint with a more recent date.

I like the Norton Critical edition of Jane Eyre. It includes several essays about the book. That might be more than you want to read, but they will help you understand the book.

It was also made into a movie.

jane eyre is a great book by charlotte bronte but it is pretty deep reading about a nanny who goes to care for what she supposes is a wealthy widower's child. but it gets very intense and involved and of course is written in period england.

you might do better with the more contemporary "the member of the wedding" which is actually about a 12 year old misfit girl.

-Because the book is no longer covered by copyright, it's likely that lots of different people have scanned it in and made their versions available via iBooks. These are all the same book, but most of these are probably full of typographical errors. If you want a clean copy that has been proofread, get the free version from Gutenberg.org, as @Marli suggested, or better yet, get a commercially published edition with the critical essays, as @Dan suggested.

I don't have iBooks, but "Jane Eyre" was written by Charlotte Bronte. You can check out "Project Gutenberg" or your local library's catalogue.
