About this book

Sometimes the apple doesn't fall far from the tree, and in the case of Caesar Di Rozé and his son, Zephyr, it couldn't be more true. I didn't intend for my one-night stand with Zeph to lead me back to his father's place, but the moment it did, it was over for me. Caesar Di Rozé is a silver fox with the most delicious dark stare I've ever seen. After spending the night with his son, he meets me in the kitchen and proves once and for all that Daddy indeed does it better. One glance, and I was addicted. But after one touch, I was ruined. That night changed it all, and when he murmured into the darkness as his son slept in the next room, daring me to return for more, I couldn't resist. Only it came with one simple caveat-a sacred vow that must be kept-under no circumstances can I fall in love with him. Easy, right? Wrong. Sacred Vow is a Dark Daddy Age Gap Romance. It contains explicit content, detailed violence, high spice, and coarse language. It is recommended for mature readers.
