Sorcerer's Legacy - Tapa dura

In Janny Wurts' Sorcerer's Legacy, we discover a world full of magic and intrigue. It is into this world that Elienne has chosen to come, to save a princes life. Lady Elienne finds herself captive in the dungeons of the one who killed her husband and conquered her lands. While there, a great wizard appears to her offering to take her away. Does she stay and suffer certain cruelties from the one who now wants to make her his new queen... Or does she go with this wizard who claims that she is the only one who can save his prince's life. Neither choice has much chance of her surviving, so neither choice looks good. But if she goes at least it will be by her own choice...
