Query: Great book - LOUSY EDITION

THIS IS A GREAT BOOK.However, this e-book edition by Macmillan is foul. Computer codes in the middle of words, chopped off paragraphs, trailing with garbage symbols... Would you enjoy reading a page of text peppered with trash characters like &apos; or "height=0em width=1em?Doesn't Macmillan have editors to proof-read the product? Or are they engaging in deliberate sabotage of the e-book market? All the while charging top dollar. This half-baked product is not worth $9.99 - it is not even worth 9 cents.Do yourself a favor - get a paper copy instead.
