I would be grateful if anyone could help me identify a book that I read but can't remember it's name, the author or the names of any of the characters - it's driving me mad! What I can remember is that it's a space opera, the main character is a crewman on a military spaceship and the ships are crewed by humans and a bear-like race. The bears have a smoking habit... The book is part of a series. I remember seeing that the author was accused or plagiarising/rehashing others ideas. Thanks.
