Henry Dawson, sorcerer and apothecary assistant, works to support his mother and younger siblings after his father's investments and consequent death leave them penniless. Invited to woo a reclusive heiress with magical empathy, he reluctantly accepts, despite a preference for earning his own way. Emma Ainsworth fears smallpox scars and her hypersensitivity to others' thoughts make her ineligible for marriage. Sheltered by her aunt and uncle, she has withdrawn from most social life and wears a veil whenever she must go out. When a serious injury confines Henry to Emma's estate for the summer, a verbal duel ensues-Emma wants to test her empathy in a sexual relationship, not marry him. What neither admits is their fear that passion might burn them both.
