Where to Start with the Billionaire’s Obsession
With over twenty books in the Billionaire's Obsession universe, the best place to start is with the book that launched the phenomenon: The Billionaire's Obsession ~ Simon. This book introduces Simon Hudson and Kara Foster, setting the stage for the interconnected families and steamy romance tropes that define the series. While each novel is a standalone romance with a guaranteed happily-ever-after, reading them in order allows you to follow the recurring characters, family dynamics, and regional transitions smoothly.

Chronological Caveats & Subseries Breakdowns
The series is organized into regional and family-based subseries. If you prefer, you can read these individual branches on their own, starting with the first book in each group:
The Hudsons, Hamiltons, & Harrisons (Tampa & Colorado)
The early books establish the core universe, following the wealthy Hudson brothers (Simon and Sam), their close friend Max Hamilton, and the Harrison siblings (Kade, Travis, and Jason) as they find love in Tampa, Florida, and the Colorado mountains.
The Colter Family (Colorado)
Starting with Billionaire Untamed ~ Tate, the focus shifts to the Colter siblings (Tate, Chloe, Zane, Blake, and Marcus) in Colorado. The series also crosses over with the Walker family during Chloe's story.
The Lawson Brothers
This trilogy follows the Lawson brothers—Jett (Billionaire Unloved), Carter (Billionaire Unchallenged), and Mason (Billionaire Unattainable)—bringing a fresh dynamic to the family saga.
California Billionaires
This subseries moves the setting to the West Coast, starting with Hudson Montgomery's story in Billionaire Undercover ~ Hudson and running through Billionaire Unreachable ~ Wyatt. The standalone romance Billionaire Unwed: Zeke (originally published as the novella Temporary Groom) is expanded and fits closely within this timeline.
Montana Billionaires
Starting with Kaleb's story in Billionaire Unexplained, this regional subseries takes readers to rural Montana. Recent releases continue the saga with Tanner (Billionaire Unforgettable, 2024), Devon (Billionaire Undeceived, 2025), and Cole (Billionaire Unforgiven, 2026).
