André needs to get back on the school fencing team, pass the Baccalauréat, and win a sports scholarship to Notre Dame. Then a broken épée and a moment of teenage heroics leave him bleeding out in a Paris street - and he wakes up somewhere much older. 

In Valhalla (the resting place of warriors who die holding a sword), André learns the truth: he's not dead, not quite, and the only way home is to complete a quest. What quest? Choose honour, he's told. That's the hint. So begins an odyssey through Roman-occupied Britain - a rebel queen with a secret, a druid who may or may not be his old fencing coach, a bear named Brutus, and a warrior maiden named Lucy, who teaches André that some things are worth fighting a war for. What starts as a cosy adventure ends in tears. Honour has a body count.
