I once read a book in the mid 80's about a village on a river. There was a demon/dragon in hybernation in a swampy wooded area until 2 young boys woke it up. The dragon/demond flew to the village and ate people. I thought it was called blood wings but I was mistaken. The cover was red and black, and I think it had a dragon on the front. I think there was something about a deal with this creature to not attack the village. I also remember the boys getting in a canue and go down the river where they found the creature. Does anyone have any idea what this book may be called. I have searched and search and would know the book by its cover emediately. Please help, this is the only book I have ever enjoyed reading and want to read it again. This book might wake up my desire to read other books.
