Night Cannot Hide the Heart

Everyone in the old part of town knew that Declan Voss, the underworld's golden heir, was like a piece of cold metal that would never warm. He was never short of women by his side, but the girl named Seraphina Voss was an exception. Sienna was someone he had been bound to protect since she was twelve, yet she was also the only thorn bold enough to smash a cup in front of him and curse him to his face, saying he was nothing more than a man leaning on his family's power. For so many years, Declan thought he'd hidden it well— having a public girlfriend, keeping the proper distance, burying that wild, growing possessiveness in the deepest place. But when it mattered most, he realized that if Sienna so much as glanced at someone else for a second longer, the walls he'd built around his heart would crumble in less than a heartbeat.
