I am looking for a book, but I cannot remember the title.?

The book is an historical fiction based on the life of a young druid boy whose village is destroyed. The boy then embarks on a galley ship for several years until landing in a port to persue his own destiny. I don't remember many of the plot points, but I do remember several. One of his adventures involves a beekeeper whom the man helps, another involving him going to prison only to escape. If anyone has any information on this book, I would greatly appreciate any help. I haven't read this book since 7th grade, although the reading level is significantly higher. The book is between 600 to 1000 pages long. I've been searching for it for years to no avail.
