Bikini Days

by Michael Dalton

2023

After a decade as a single dad, Ethan has accepted that raising his daughter Maddie is his whole world. When Maddie’s best friends Lexie and Olivia lose their apartment and move in, friendly support turns into a slow-burn, age-gap menage that forces all three adults to redefine love, family, and their future.

Series background & context

Bikini Days steps away from magic and monsters and into a contemporary beach town, while still keeping Dalton's focus on unconventional relationships and found family. The series follows a middle-aged single father who has spent a decade putting his own life on hold to raise his daughter after a brutal divorce.

When his daughter's best friends, Lexie and Olivia, lose their apartment and have nowhere else to go, inviting them to stay feels like the obvious, decent thing to do. They were there for his daughter during her worst years, and taking them in is a way to pay that kindness forward. What he is not prepared for is the slow, undeniable shift in how they all see each other.

As the three adults navigate cramped quarters, shared routines, and late-night conversations, attraction turns into something deeper. The books explore how an age-gap, multi-partner relationship might actually function day to day: who does the chores, how jealousy is handled, what happens when extended families push back, and how you talk to a grown child about loving her friends in a very different way.

Later volumes widen the circle. His daughter Maddie and her friend Meredith get more of their own arcs, bringing new emotional entanglements and questions about independence, boundaries, and long-term plans. The arrival of Ariella, a character with ties to Dalton's supernatural fiction, nudges the story closer to his wider universe without turning it into a fantasy.

Through it all, the tone stays grounded. There are explicit scenes and plenty of heat, but the heart of the series lies in quiet domestic moments: cooking dinner, studying for classes, planning weddings, and figuring out what "family" means when it no longer looks anything like the picture on a greeting card.

Bikini Days is ideal if you want a romance that feels like it could exist in the real world, with characters who talk through their flaws and fears instead of being swept away by a single grand gesture. It shows Dalton applying his harem storytelling instincts to a setting where the biggest threats are disapproving relatives, old wounds, and the challenge of growing together instead of apart.
