Covey, originally from Jamaica, carries the weight of her past like an anchor, especially after fleeing to England under a fake identity. Her daughter Benny is a free spirit with a passion for art, always clashing with her more traditional sister, Bunny, who chose stability over adventure. Then there's Mabel, Covey's childhood friend-turned-enemy, whose choices ripple through generations. The story unfolds through their perspectives, revealing how one woman's choices can alter an entire family's destiny. Each character feels painfully real, making you root for them even when they mess up.
