Diagnosed with cystic fibrosis at the age of three, Mallory Smith grew up to be a determined, talented young woman who inspired others even as she privately raged against her illness. Despite the daily challenges of endless medical treatments and a deep understanding that she’d never lead a normal life, Mallory was determined to “Live Happy,” a mantra she followed until her death.

The fire wasn’t Marlowe Wexler’s fault. Dates should be hot, but not hot enough to warrant literal firefighters. Akilah, the girl Marlowe has been in love with for years, will never go out with her again. No one dates an accidental arsonist. With her house-sitting career up in flames, it seems the universe owes Marlowe a new summer job, and that’s how she ends up at Morning House, a mansion built on an island in the 1920s and abandoned shortly thereafter. It’s easy enough, giving tours. Low risk of fire. High chance of getting bored talking about stained glass and nut cutlets and Prohibition.

The last two people she wants to run into.

Calvin knows how to pass for white. He's done it plenty of times before. For his friends in Chicago, when they wanted food but weren't allowed in a restaurant. For work, when he and his dad would travel for the Green Book. This is different. After a tragedy in Chicago forces the family to flee, they resettle in an idyllic all-white suburban town in search of a better life. Calvin's father wants everyone to embrace their new white lifestyles, but it's easier said than done.
