Odyssues and other heroes

In the book "Bec"by Darren Shan, one of the heroes,Drust, reminds me of Odysseus from the Odyssey. Both characters share similar traits in my opinion. The thing that I thought was the most similar was when any of their team mates die they do not give up or let it affect them too much. I think someone has to be very strong to not let the death of an ally affect them and their mission or quest.
