When her ambitious, vain sister refuses to marry the infamous billionaire Killian Thorne after a brutal accident leaves him paralyzed, Lyra Sinclair is dragged from her quiet rural life to take her place as the substitute bride. Cast into a cold, heavily guarded mansion of a man believed to be a bitter monster, everyone expects Lyra to cower. They expect her to break. They don't know who she really is. Armed with an old leather pouch of silver needles and a razor-sharp clinical mind, Lyra looks past the cold glares and the broken legs. She sees a man bound by chemical lies and vicious family betrayal—and she refuses to let him lose. As the silver needles pierce through the agony, a fierce, suffocating chemistry ignites between the cold corporate tyrant and the fearless healer. But when the day of reckoning arrives at the grand high-society gala, the man presumed crippled stands tall before a thousand terrified traitors—ready to reclaim his throne, destroy his enemies, and claim his queen for eternity. He falls first, but he falls harder. And God help anyone who tries to touch his wife.
