I was enjoying this book up to a point, a Gaulish warrior traveling through Caesar's Rome to Persia. The perspective was interesting. I felt like it was going to be a solid rec for people who love Shogun etc.
Then it got to Greece and the portrayal of two young teens sexuality was deeply horrible. It's a subject that takes a delicate hand, but this went somewhere beyond being clumsy, into territory that I found deeply repulsive.
