Voice of the Demon: The Books of Elita #2

The second in a glorious epic of political intrigue, sorcery and romance: an ancient prophecy and a new evil threaten the country: perfect for fans of Robin Hobb and Elizabeth Moon. The Prophecy of the Key is coming to pass, promising chaos and destruction for Lusara and its people. Robert Douglas, the new Duke of Haddon, has been banished from the sorcerers' hidden colony, for he will neither bow to the will of the ruling council, nor will he use his banned magical powers to overthrow the usurper King Selar.
But he cannot hide out at his estate, for his reckless brother Finnlay, believed dead by most of Lusara, has left the Enclave and is headed straight for trouble. And Jenn needs his help again too. She's been learning to live the life of a noblewoman whilst secretly using her own powers to help those fighting the Guide's punitive new laws - but Lusara's queen has asked for her help, leaving her no choice but to call on Robert and the Bond they share .
