Poison Doctor Empress: Your Majesty, Don't Skip Your Meds!

When a brilliant 21st-century special agent and miracle doctor dies in an explosion, she awakens in the body of a scorned noblewoman in ancient times. Armed with deadly poisons, medical genius, and zero tolerance for betrayal, she declares war on everyone who wronged her predecessor. Scumbag fiancé? Dumped and beaten beyond recognition. Scheming stepsister? One dose away from regret. But when the enigmatic emperor sets his sights on making her his empress, she faces her greatest challenge yet—a man who refuses to take his medicine and won't take no for an answer.
