Love Locked In [EPUB ebook] 

Aristide, the Duc de Savigne is literally Lord of all he surveys – including the women who throw themselves at his feet only to be trampled and scorned. Arrogant and promiscuous, his wild orgies and rampant behaviour are ‚defaming the name of Savigne and making it a byword for every outrage, scandal and vice…‘
Yet, when asked to marry this man without even meeting him, innocent beauty Syrilla happily agrees. Even when she finds herself bride to this embittered man, obsessed with his love for a murdered Chère amie she adores her ‚White Knight‘ with a passion… Can it be that her pure unsullied love is the key that frees his locked-in-heart?
