Queen of Storms. Book Two of The Firemane Saga

Dark and powerful forces threaten the world of Garn once more in this second novel in legendary New York Times bestselling author Raymond E. Feist's epic fantasy series, the Firemane Saga. Hatushaly and his young wife Hava have arrived in the prosperous trading town of Beran's Hill to restore and reopen the fire-damaged Inn of the Three Stars. They are also preparing for the popular midsummer festival, where their friends Declan and Gwen will be wed.
But Hatu and Hava are not the ordinary loving couple they appear to be. They are assassins from the mysterious island of Coaltachin, home to the powerful and lethal Nocusara, the fearsome "Hidden Warriors." Posing as innkeepers, they are awaiting instructions from their masters in the Kingdom of Night. Hatu conceals an even more dangerous secret. He is the last remaining member of the legendary Firemanes, the ruling family of Ithrace.
Known as the Kingdom of Flames, Ithrace was one of the five greatest realms of Tembria, ruled by Hatu's father, Stervern Langene, until he and his people were betrayed. His heir, Hatu-then a baby-was hidden among the Nocusara, who raised him to become a deadly spy. Hatu works hard to hide his true identity from all who would seek to use or to destroy him, as fate has other plans for the noble warrior.
Unexpected calamity forces him to make choices he could not have dreamed awaited him. A series of horrific events shatters the peace of Beran's Hill, bringing death and devastation and unleashing monstrous forces. Once more, the Greater Realms of Tembria are threatened-and nothing will ever be the same again.
