The Sundered Realms by Casey Blair

Nannying children has always been an adventure on its own, each different than the last. It’s how I’ve made it my living, and it’s something I genuinely enjoy. But leaving all of that behind becomes easy when I have to return to San Francisco to look after my dad after a major health scare that puts things into perspective—like how important my own family is.
But after an allegedly accidental fire takes everything from me, there’s only one person that can help—Bruno Cataldi, San Francisco’s most feared mob boss. The catch for asking for his help? I have to be the live-in nanny for his kids.
Now, I’m living in the house of a renowned criminal, looking after his adorable twins, while fighting arising feelings for a man nearly twenty years my senior. I had never wanted to be a cliché of a nanny falling for the father of the kids she’s caring for, but that feels impossible with a man like Bruno Cataldi suddenly in my life.
