Birthday Girl

True love comes from the most forbidden places in this TikTok smash hit from New York Times bestselling author Penelope Douglas, now with bonus material!

Jordan has nowhere else to go when her boyfriend offers to let her move in with him and his dad. Working a dead-end job, with her relationship sputtering, she jumps at the opportunity, expecting to help out around the house in exchange.  What she doesn’t anticipate is for her heart to race every time Pike pulls into the driveway, or to burn when their eyes meet over the breakfast table. He’s kind and listens to her and protects her in a way no man ever has before. Her sister once told her there are no good men, and if you find one, he's probably unavailable. Only Pike isn't the unavailable one…she is.

As the days go by, Pike’s finding it anything but simple to have his son’s girlfriend living in his house. He can’t stop thinking about her and holding his breath every time they cross paths. It feels like she’s becoming a part of him. Except he knows they’re not free to give in to this. How could they when he’s her boyfriend’s father?

Pike is my other book boyfriend next to Reed. Relax… it’s not cheating if it’s fiction. Loved the yearning and the fire in this one. 🔥 One of the best age-gap (totally legal) stories I’ve read.

Penelope Douglas delivers a masterclass in slow-burning tension. This isn’t just about banter—it’s the loaded pauses, the subtle shifts in body language, and the kind of non-verbal cues that speak louder than dialogue. She creates characters you can see in your mind, down to the way they breathe around each other.

Our MMC, Pike, stood out because he recognized that everyone in Jordan’s life had let her down. Her mom didn’t want her. Her dad lived as if she didn’t exist. Her sister loved her but never respected her. Cole? He took advantage, whether he meant to or not.

Pike’s approach was different—intrusive interventions, sure, but rooted in care. He seemed almost unconscious of how much he made her feel seen, heard, and wanted. For the first time, someone showed her love beyond the basics of a roof, money, and food.

Pike being 35+ was a refreshing choice—mature without being a broody caricature. But we can’t ignore the elephant in the genre: where are the FMCs in their 30s? Romancelandia still loves its late-teen/early-20s heroines, but an unmarried, child-free 30+ woman is absolutely loveable, desirable, and worthy of a first-page meet-cute. In fact, that kind of heroine carries more emotional texture and real-world resonance.

DNF. Cringe. Horrible dialogue. Just no.
