Unendurable . This book was on somebody's Amazon.com LISTMANIA for Sea Turtles, so I hunted it down. It is only vaguely about sea turtles, in that it is set on an island in Georgia where sea turtles nest. There is a sea turtle biologist introduced at the very beginning of the book, and then he disappears, so it's obvious that he was involved in the crime. There are way too many characters in this book to keep track of and most of them are not believable or likable. I wish this book had at least been fun to read but it was tedious and I ended up skimming the whole thing, looking for any sign of sea turtle interaction. Skip this book and send your $6.99 to a sea turtle hospital instead.
Output:
NEG
