The 'Billionaire' series is one of those sprawling sagas that feels like it never ends—in the best way possible! From what I've gathered, there are at least 12 mainline books, but that number doesn't even include spin-offs or novellas. The first few, like 'Billionaire Untamed' and 'Billionaire Undaunted,' hooked me with their mix of high-stakes drama and over-the-top romance. The later entries, though, started blending corporate intrigue with family sagas, which gave the whole thing a 'Succession' but with more champagne vibes. I lost track after book 10, but a quick dive into fan forums confirmed the count. Honestly, half the fun is debating whether the side stories 'count'—some readers swear by the unofficial tie-ins!
What's wild is how the tone shifts over time. Early books are pure wish-fulfillment: private jets, enemies-to-lovers tropes, you name it. By book 8, though, the author started weaving in darker themes like inheritance wars and moral gray areas. It’s almost like two different series smashed together. If you’re new to it, I’d say pick a sub-genre you love (revenge plots? fake relationships?) and jump into those installments first. The continuity’s loose enough that you won’t get lost, and the Easter eggs for long-time fans are a nice bonus.
