Basic Cantonese: A Grammar and Workbook (Grammar Workbooks)

I actually own the hard copy but wanted the ebook version for my ipad library for convenience. I wasn't too happy when I noticed that all of the text (though the pictures have it) did not include tone marks for the first (high pitch) tone...rendering the book useless to any learner.
