Drake, David, 1945- Time of heroes series.

Young knight Pal is one of the most respected members of Lord Jon's Hall of Champions. But Pal's greatest talent lies not on the field of battle, though he's no slouch there. He is also a Maker, one who can repair the tools the Ancients had left--sometimes. Moreover, he has learned to use his warrior dog's ability to predict motion better than any human could, an ability that has saved his skin and won the day more than once.
