A young boy named Bai Wu was saved and adopted by a thirty-something police sergeant named Xu Lan. It was love at first sight for Bai Wu, and once he started getting older, his heart yearned for a taste of the forbidden fruit – the romantic love of his adoptive father. The question is, will Xu Lan ever reciprocate? With deranged serial killers, parallel dimensions, time warps, dragons, and a bit of ancient black magic, Bai Wu and Xu Lan are caught in a series of crazy adventures while discovering what they truly mean to each other. This is a story of lust and madness!

200 years after the world has ended, the laws of society have long been forgotten.

Now, Elias is stuck raising the former destroyer of worlds—who can barely tie her shoes, but occasionally melts furniture when she pouts.What starts as reluctant guardianship soon spirals into something far more dangerous. As Rhea (her new alias) grows stronger, older, and far too attached, Elias must keep her identity hidden from zealous church inquisitors, ambitious heroes, and the remnants of her own loyal followers—some of whom want her dead... again.But the longer he protects her, the deeper the bond grows—and the harder it becomes to tell who’s really taming who.Because the world once burned beneath her wings……and this time, she’s not letting him go.
