"Falling from Heaven" is a novel by Olga Oliye, the fifth book in the eponymous series. Genre: romantic fantasy, adventurous fantasy, domestic fantasy.
Falling in love with your enemy? In a nightmare, maybe. But for me, this nightmare turned out to be real. And it wasn’t just that I fell in love. The one I gave my heart to even tried to kill me. To end up in a cell and find out that you’re not really you—that you’re, in fact, an infestation/possession? That could only happen to me. But no matter—figure it out, save everyone, and outwit death. And at the same time I’ll have to find out who I am, really.
