Checkmate

When sword for hire Teodoro Cieza de Vivar accepts a commission to "rescue" Lord Christian Blackwood from unsuitable influences, he has no idea he's landed himself in the middle of a plot to assassinate King Philip IV of Spain and blame the English ambassador for the deed. Nor does he expect the spoiled child he's sent to retrieve to be a handsome, engaging young man. As Teodoro and Christian face down enemies at every turn, they fall more and more in love, an emotion they can't safely indulge with the threat of the Inquisition looming over them. It will take all their combined guile and influence to outmaneuver the powerful men who would see them separated... or even killed."
