By day, Dr. Vivienne Chen fights corporate developers to save the crumbling Wellspring Cathedral, sensing something special in its ancient stones that others cannot feel. By night, she works alone in its shadowed halls—until she discovers she's not alone at all.

When gargoyle guardian Elias Reed awakens from his stone slumber each sunset, his powerful body transforms from cold granite to hot flesh. For 250 years, he's maintained his solitary vigil—until he catches the scent of the passionate preservationist whose delicate fingers trace the cathedral walls as if they were a lover's skin.

Despite his imposing winged form and inhuman strength, Viv isn't intimidated—she's aroused. As moonlight streams through stained glass, their forbidden attraction ignites into searing encounters against centuries-old stone. Between her breathless moans and his primal growls, Elias teaches Viv that his granite exterior hides desires that have been centuries in the making, while she awakens sensations in him long forgotten.

But their passion is measured in shadows—each dawn cruelly reclaiming his flesh, leaving Viv clutching cold stone. When she uncovers an ancient ritual in the cathedral's secret archives that might break his curse, they face a devastating choice: risk destroying the very sanctuary that binds them, or condemn their burning desire to the torture of touch only in darkness.

With developers closing in and the cathedral's demolition looming, Viv and Elias must discover whether the heat between them can shatter a centuries-old spell. In the race against daybreak, they'll learn if pleasure can truly turn stone to flesh—before they lose each other, and the cathedral, forever.
