The Magehound (Forgotten Realms: Counselors & Kings, #1)

Some are born with magic.
Some without.

Matteo, un-magical counselor to the mighty of Halruaa, has devoted his life to the truth -- until he finds that he may have a hidden spark of magic after all. Now, with only a street waif for a companion, he's on the run from the mysterious Cabal. In the dismal Swamp of Akhlaur, Matteo will seek his own truth while battling a creature out of his nightmares.

But something even worse is on his trail: a relentless persecutor of magic. The Magehound.
