Being married to your best friend isn’t as easy as it sounds.

Grace Hart wants a baby. Nearing forty, with no husband and no fairy-tale ending in sight, she’s decided it’s time to take control of her future. Her perfect partner? Her best friend of twenty years. Caz Madden has always been there for her—loyal, kind, and dependable—and Grace is sure together they can create the family she’s always dreamed of. One tiny complication? Grace is straight. Caz is very much not.

Caz knows agreeing to Grace’s plan is madness. She’s always been close to her best friend—maybe too close—but she’s never dared to question why. When their marriage of convenience begins, the lines between friendship and something deeper start to blur, forcing Caz to confront feelings she’s spent a lifetime not naming.

As blurred boundaries become something dangerously real, Grace and Caz must decide whether the love growing between them is worth risking the friendship that has always been their foundation.

The Last to Know is a heartfelt, slow-burn sapphic romance about friendship, family, and the courage it takes to fall for the one person you were never supposed to love.
