Twisted Love By Ana Huang

He has a heart of ice… but for her, he'd burn the world. Alex Volkov is a devil blessed with the face of an angel and cursed with a past he can't escape. Driven by a tragedy that has haunted him for years, his ruthless pursuits for success and vengeance leave little room for distractions—until his best friend's innocent little sister, Ava Chen, crashes into his life. She’s sunlight incarnate, a vibrant artist who sees the good in everyone, including the man everyone else fears. What starts as a simple favor—watching over his best friend's sister while he’s overseas—turns into an all-consuming obsession. Alex will do anything to protect her, even if it means risking his own heart. But when secrets from his past threaten to destroy everything, can their twisted love survive? A steamy, addictive romance perfect for fans of emotionally charged, brother's-best-friend tropes.
