When Colin studies at Oxford, an eccentric but brilliant professor, Dr. Phineas Teague, guides the young man to a career in medicine. The formal knowledge Professor Teague imparts, combined with knowledge of Meg's herbal remedies, make Colin an insightful and successful doctor-one with the approving eye of Queen Elizabeth on him. Colin's skill quickly earns him many patients, some highly placed in the courts of both his queen and her sister Mary Queen of Scots. This once shy and uncertain young man finds himself in the midst of court intrigue and a key player in quelling assassination plots and passing vital information to the queen's court. When Colin faces his most difficult case-curing the wounds his brave brother suffered in battle-he must confront his attraction to Adam's wife, his unsteady faith in God, and his command of medicine: will he abandon his noble role and succumb to temptation, or will he take his place as the new hero of the Breed of Winslow?
