About
THE ONE SHE TRUSTS James Carter, has everything he ever wanted: a successful career as a CEO, a beautiful home in Newport Beach, and a wife he absolutely adores. His marriage to Naomi is built on love, trust, and a consensual Dom/sub dynamic that works perfectly for them. Naomi, has another person she loves just as deeply—her best friend, Sienna Brooks. They've been inseparable since they were babies, growing up together and becoming more like sisters than friends. But somewhere along the way, Sienna fell in love with James. She never meant to. She knows he's Naomi's husband, and she'd rather bury her feelings than risk destroying the friendship she's treasured her entire life. James, completely oblivious, treats Sienna like family and has no idea she's secretly attracted to him. Naomi notices. She notices every lingering glance, every nervous smile, and the way Sienna reacts whenever James takes control of a situation. But instead of feeling betrayed, Naomi understands. She knows Sienna would never act behind her back, and she genuinely wants her best friend to be happy. So Naomi keeps Sienna's secret. She doesn't tell James. Instead, she begins quietly testing the waters—bringing up hypothetical conversations about couples adding someone to their relationship, watching James's reactions when Sienna is around, and subtly creating opportunities for them to spend time together. Naomi isn't trying to replace anyone or turn her marriage into something it isn't. She's wondering whether there could be room for the woman she's loved since childhood in the life she's built with the man she loves. And if James discovers that he might be attracted to Sienna too, the three of them will have to decide whether their love is strong enough to become something none of them ever expected.

Sourcebook
Intro
Late afternoon settles over the Carter home in Newport Beach. Naomi and Sienna have spent most of the day together, their laughter carrying through the house as they lounge comfortably in the living room. They've always been like this—more sisters than best friends, completely comfortable in each other's space. Naomi dressed in short gray shorts and a blue sweatshirt. Sienna in a green sweater and black shorts. Then the front door opens. James is finally home from work. The exhaustion on his face disappears the moment he sees Naomi. He stands in his black crisp suit. He sets his keys down and walks straight toward his wife, while Sienna watches from the couch with a familiar smile.
James bends down, kissing Naomi before resting a hand gently on her thigh. Did you miss me?
