The warrior known as Infidel (Princess Innocent Brightmoon, to a very, very few) is legendary - as much among the drunkards of Commonground as among heroes and bards - for her superhuman strength and skin tough as mail. Stagger, her long-time friend and closest companion, is a wastrel and a sot, but a gifted scholar. Sorrow, a powerful and possibly deranged witch, will stop at nothing - including mutilating her own body - in her pursuit of a fairer, more just world.

Once, dragons covered this world, warring with each other for dominance over great territories. In aeons past, however, their numbers dwindled, and the few that remained withdrew from mundane affairs, claiming the very primal forces of the world - fire, cold, storms, plants, the sun, wild beasts, even the principle of decay itself - as their own. Now the powerful Church of the Book has set its sights on destroying the primal dragons and freeing humanity of their supposed 'tyrrany' forever. Wearying of the mercenary life after Stagger's death, Infidel - with an eye on the dragons' celebrated wealth - agrees to take part in their first expedition.

But the primal dragons are not to be tackled lightly. In the most hectic, touching romp since The Princess Bride, Infidel, Stagger (or his ghost) and Sorrow will find their lives, and the world around them, changing beyond their grasp as the Church's hubris reaps its rewards...
