At nineteen, Y/n knows better than to fall for her dad's best friend. Jon is older, protective, off-limits, and has been around for as long as she can remember. He's the man her father trusts more than anyone-the one person she should never look at the way she does. But everything changes during one family road trip. When unexpected circumstances leave Y/n riding alone with Jon for hours, stolen conversations, lingering glances, and undeniable chemistry begin to blur the line between friendship and something far more dangerous. The closer they get, the harder it becomes to ignore the feelings they've both tried to bury. Keeping their distance was supposed to be easy. Keeping their hearts out of it? Not so much. Will they risk everything for a love that could tear a family apart, or will some rules prove impossible to break?

"You should stop looking at me like that, Maddie." "Like what?" "Like you want me to do something about it." • Maddie Hayes knows better than to get involved with Frank Castle. Frank knows better than to touch a woman like her. He's older. Guarded. Dangerous. And definitely not the kind of man she should be having late-night conversations with at the bookstore where she works. But attraction has a way of making bad ideas seem reasonable. What starts with stolen glances, sarcastic conversations and an unexpected discovery that they live in the same building eventually becomes a simple arrangement. No expectations. No feelings. No strings attached. At least, that's what they're telling themselves. Because Maddie has a secret. One she's spent years making sure nobody discovers. And if Frank ever finds out what she's capable of, their little arrangement could become the least of their problems. Some secrets don't just threaten to ruin a relationship. They can turn lovers into enemies. 18+ | age gap | slow burn | situationship | dangerous attraction | forbidden attraction | tension | spicy | Frank Castle x OC

Frank Castle has spent thirty years being the one man Dean Whitaker trusts completely. Now he's divorced, between homes, and sleeping in Dean's guest room, three doors down from Dean's daughter. Jane is 23, bold, and bratty, and she has never been shy about pushing his buttons. She's also the one thing he is not allowed to want. Frank knows where the line is. He drew it himself. But Jane is done being the good girl her father shows off and hides away. Every shared kitchen, every lingering look, and every "accidental" wrong outfit is making that line harder to see. With a winter storm on the way and four miles of dirt road between them and anyone else, restraint is running out. Some rules are meant to be broken. Some friendships to be tested and some men to be pushed too far.

And it's absolutely not supposed to get complicated. Except Frank is nothing like the man Kate left behind, and the more time she spends with him, the harder it becomes to remember where the act ends and her feelings begin.
