Lucie’s newest doctor is devoted, attentive, and dangerously desirable. When he proposes to liberate her from a suffocating betrothal, she leaps at the chance, despite knowing nothing of the enigmatic man’s past. Driven by desire, she abandons her sure future and escapes with him, crossing Europe on an adventure that will challenge everything she knows of love. Doctor he may be, but her new husband Matthias is an unrepentant libertine, with an unerring sense of whom to seduce into his curious experiments, and when to cut all ties and run for his life. Yet she cannot doubt his love, for she feels the very same, no matter the peculiar forms their romance will take. For something—someone—calls the doctor ever onward. A love lost to time. A love he cannot forget. His ruin, again and again. And at times his salvation. A deeply sensuous polyamorous romance set amid the decadence and despair of fin-de-siècle Europe.
