To the forest on the shore of the Kingdom of the Isles, the orphan Pug came to study with the master magician Kulgan. His courage won him a place at court and the heart of a lovely Princess, but he was ill at ease with normal wizardry. Yet his strange magic may save two worlds from dark beings who opened spacetime to renew the age-old battle between Order and Chaos.

A poisoned bolt has struck down the Princess Anita on the day of her wedding to Prince Arutha of Krondor. To save his beloved, Arutha sets out in search of the mystic herb called Silverthorn that only grows in the dark and forbidding land of the Spellweavers. Accompanied by a mercenary, a minstrel, and a clever young thief, he will confront an ancient evil and do battle with the dark powers that threaten the enchanted realm of Midkemia.
