A pact made in youth to navigate a restrictive society leads two friends down a path of hidden desires and unforeseen tragedy. Bettina and Bart, childhood best friends, find themselves in a predicament in 1921: their mutual attraction is purely platonic, yet societal expectations and their own burgeoning homosexual identities push them towards a 'lavender marriage'. Bettina's true desires manifest in a torrid encounter, while Bart's are explored during a Parisian sojourn. They enter into their marriage of convenience, seeking to indulge their true natures in secret amidst the roaring twenties and thirties, unaware that their lives are hurtling towards a dramatic and bloody conclusion across various international locales.

This novel has been praised for its blithe, witty, and moving narrative, drawing comparisons to Nancy Mitford's style adapted for a gay sensibility. Critics highlight its humor, described as 'funny, filthy and phenomenally good,' suggesting a bold and engaging tone. The premise of a lavender marriage in the early 20th century sets up a narrative that balances personal desires with societal pressures. The story appears to blend historical context with a contemporary exploration of identity and relationships, promising a rich and engaging reading experience.
