Catharina Maura―the highly anticipated, standalone spin-off of the Windsors series. When the man she's always been in love with starts dating one of her friends, artist Serenity Adesina creates a to-do list that will help her get over him once and for all. The first item on that list? Losing her virginity to Archer Harrison, her older brother's billionaire best friend…and her boss. He's the perfect choice―alluring, caring, and entirely emotionally unavailable. Their deal was supposed to be simple: Serenity will paint Archer anything he wants in return for a secret, no-strings-attached relationship. Except each kiss leaves them both wanting more, tempting them to risk it all for what's growing between them. That is, until a cruel twist of fate shows them that giving in to their feelings comes at a far higher cost than they could've imagined.
