Nothing Special...
Most people I know have to read the book at some time in high school or college; this cliffs note guide offers generally the same type of review information you could find for free online, though of course its trim paperback format makes it a more convenient, portable size for flipping through and taking notes in while in a line or a waiting room. I got it for free or a sale (it's been awhile) with the book The Odyssey itself but didn't find it to be a particularly helpful companion to the book. I'd suggest just taking notes as you read and useing them.
The Odyssey
If you are in a hurry to complete your report, it will help you so. But don't forget to read the entire book as soon as you can.
Surprisingly thorough
The important details of every Book are explained and analyzed, not very much in-depth but deeply enough to give a basic understanding of what's going on, why, and how it might be interpreted. I had read the Odyssey twice in the past (and remembered almost nothing), so this was a great way to refresh my memory without having to read the epic for the third time for a course.
It is not intended to replace reading the actual epic, but it does help make it more accessible to all. Good work.
TURNED "ROCKET SCIENCE" to Reading Ease
Homer's The Odyessey is a drudgery to read not to mention understand. This book took the pain and bordom of that and shortned it to a 1 hour (45 if your a fast reader) book that keeps all the details (for your reading pleasure) and explains the importance of each section in relations to High School which actually helps a ton. (pulled my grade on this from the usual B to A thanks to this book).
Cliffnotes
This is a great way to help you better understand the book. While it does not take the place of the book it is a really good learning tool,
