A Wizard of Sorts. Misfits of Gambria, #4

Murder, intrigue, suspense, and romance - all set in a medieval rivalry of two kingdoms at war. With Diad shipwrecked on a deserted island and Alric on the run somewhere in the north, Bradwr solidifies his claim to the throne. That means eliminating all threats. The first to go is Guina. Though no longer a viable threat, she can't remain in Mull and the former queen is forced to live on the handouts of friends far away from the capital.
The second to go is Alric. Though he is now Bradwr's son-in-law, Alric has more claim to the throne and despite the promise to Pavia of his safe return, Bradwr orders that his son-in-law have an unfortunate accident - a permanent one. Amidst the turmoil, Alexis manages to transgress Gambrian custom and finds herself at odds with the new King. Unwilling to obey, she escapes to the south, taking the nation's Tarrac with her.
But Bradwr has a blind spot and overlooked another's ambition, someone who desperately wants to rule Gambria - alone. And she might just pull it off. All she'll need to do is get rid of her husband and her father.Yet the one person they have dismissed as dead, the Ghost in the desert, is about to give them the surprise of their lives.
