Poison Study by Maria V. Snyder

Choose: A quick death or slow poison…

On the eve of her execution for murder, Yelena Zaltana is offered an incredible reprieve – on the condition that she becomes the food taster for the military leader of Ixia, Commander Ambrose.

Avoiding poison is the least of her troubles, however General Brazell, father of the man she killed, has vowed bloody revenge; she's beginning to have feelings for her captor, Valek; and someone is plotting the downfall of the current regime.

In a desperate race against time, Yelena must learn to control the growing magical talent within her and master the demons of her past. The Commander's life, the future of Ixia and all those she loves depend on it.
