Libby Lomax's attempts to return to a normal life are complicated by the reappearance of a former flame and an unexpected, spectral houseguest. Libby is trying to move on after a high-profile breakup and focus on supporting her friend Ollie's new restaurant. However, her resolve is tested when her ex, Dillon O'Hara, returns, more charming than ever. Adding to the chaos, the ghost of Marilyn Monroe appears on her sofa, making Libby long for a return to her previous, less complicated existence.

The premise sets up a lighthearted romantic comedy with a supernatural twist, likely appealing to readers who enjoy contemporary romance with a touch of the whimsical. The inclusion of a historical icon like Marilyn Monroe suggests a blend of modern dating woes with a classic, perhaps aspirational, element. The narrative appears to focus on Libby's personal growth and romantic choices, balanced with the comedic potential of her unusual houseguest. The comparison to Emily Henry and Josie Silver indicates an expectation of witty dialogue and feel-good storytelling.
