In The Dragon on the Border, Sir James, the Dragon Knight, faces his
most terrifying challenge--the Hollow Men, spirits of the dead in empty
suits of armour. Their weapons are all too real, and a slain Hollow Man
can be resurrected within two days. As long as one of their unholy
number endures, no Hollow Man can ever truly die It's a battle that
could test any dragon. Not to mention a knight. Or an American. Or all
three in one!
