Secret Billionaires is a nine-book romance series by Blair Babylon. Starting with Working Stiff (2016), the series uses cocktail-themed puns for its titles — Stiff Drink (2017), Hard Liquor (2017), Strong Spirits (2023), Hot Toddy (2023) — while following billionaires who keep their wealth hidden from the people they fall for.
The “secret” in the series title refers to characters who disguise their financial status, creating tension when their true identity is revealed. Babylon published the series in two main bursts: the early books in 2016-2017, and later additions including One Night in Monaco (2020), Hard Work (2021), Strong Spirits (2023), and Hot Toddy (2023). The series also includes Stiff Drink: Arthur Duet #1, which connects to the broader storyline through the character Arthur.
Readers looking for billionaire romance with humor will appreciate the wordplay in the titles and the lighter tone Babylon brings to the subgenre. The books share a world, so reading them in order helps keep track of recurring characters and relationships.
