Queen of Diamonds - Starlight in Aeldenarth Book Three

Half-human Princess Yavenna has found out that the mages who pursued her and her guard Gared in Shenya, have orders to take her alive. Yet even after killing two of them, and losing half a finger to another, she has no idea why. All she knows is that she is in serious danger, and that she now has no choice but to search deep inside herself to find how to wield the extraordinary magic bound to her Ithrim blood.
But when Yavenna hears the shocking news from Tarhasta that King Yeroz has died - naming her his heir - she realizes she must claim the throne before she does anything else. When she discovers that powerful forces are opposed to her becoming Queen, she agrees to let Gared and Torun stay to help her - against her better judgement.
As their danger increases, Yavenna's feelings for Gared grow, and she knows that she will soon have to make hard choices about her future. But she must choose her way carefully - the wrong decision could shatter her heart, as well as her country.
