Series information from Goodreads.

"A strange darkness grows in Allward. Even Corayne an-Amarat can feel it, tucked away in her small town at the edge of the sea. She soon discovers the truth. She is the last of an ancient lineage--and the last hope to save the world from destruction. But she won't be alone. Even as darkness falls, she is joined by a band of unlikely companions: a squire, forced to choose between home and honor, an immortal, avenging a broken promise, an assassin, exiled and bloodthirsty, an ancient sorceress, whose riddles hide an eerie foresight, a forger with a secret past, a bounty hunter with a score to settle. Together they stand against a vicious opponent, invincible and determined to burn all kingdoms to ash, and an army unlike anything the realm has ever witnessed"--
