Cruel Promise (Oryolov Bratva #2) by Nicole Fox (Romance fiction writer)

"It started with an accidental dirty voicemail. It ended with my boss's baby in my belly. One butt dial changed my life forever. Ruslan Oryolov went from boss to baby daddy in the blink of an eye. But other stuff changed along the way, too. I learn who Ruslan is, who he REALLY is. I learned that the children I've come to love as my own can't stay in this city anymore. I've learned that none of us can. So we're running. But of course, Ruslan won't let us go that easily. And when he learns about what I'm taking from him, the baby in my belly, he makes me a promise. A very, very cruel promise. No matter where you go. No matter how far or fast you flee. I will always find you." - back cover.
