Many of the editions by this group of authors are actually guides to books rather than the works.
If the author of the SparkNotes is known, they should be the first author. Please leave these SparkNotes Editors as the second author and the author of the original work as the last author. Do not combine with the original work. Do not put the author of the ORIGINAL work first.
A solid Agatha Christie--10 people on an island, all with sketchy pasts. One by one they get knocked off-how does this happen. Agatha resolves it at the end.
The book might get rated higher but I am in the midst of some awesome reading.
