Here are the problems with using this in the classroom:1. The lines are not numbered, so students will have to number the lines as homework for every scene, or else you'll waste a lot of class time doing this.2. The paper quality is terrible for annotating: Mechanical pencil lead gets caught on the fibers, and any ink but ballpoint pens spreads out.3. Very few terms are annotated in the book, so you'll need to keep your own glossary inside the front cover because there's very little space to annotate.4. Prestwick House has an annotated copy with line numbers, plenty of space in the margins, high-quality paper, scene-by-scene glossary in the back, reader's tips for reading Shakespeare, and extra textbook-type help. Guess how much: 99 cents!

Ex Output:

this DeLonghi DFH550R heater is an extremely poor product and the customer service is non-existent,doesn't have a physical address or phone number and never gives their names...buyer beware...read their absolutely ridiculous return policy before buying...if you open any package they won't take it back...if you write a truthful negative feedback, they'll be after you like " ticks on a hound " !!!

Negative

This was the first novel I've read by Shari MacDonald. It was great. She ranks right up there with Lori Wick and Lori Copeland. This is a must read.
