Vagabond (The Grail Quest, #2)

Doubting any of it at first, he gets involved in other batles before being forced into action.
There's a lot of wandering from place to place, which wile introducing plenty of new characters doesn't do much to keep the interest up. It feels as though Thomas moves around so much just to squeeze him into the historical battles of the time.
The battle scenes are well written, and there are some tense moments.
