The Billionaire's Legacy (Rachael Thomas) Books in Order

The Billionaire's Legacy is a glossy multi-author family saga built around the wealthy Di Sione clan. These books are full of money, old grudges, international travel, and emotional baggage that has been locked away for years and suddenly has to be opened. If you like continuity series where every branch of the family carries a little damage, this one does that well.

The thread linking the stories is legacy in the most literal sense. The Di Sione grandchildren are drawn into a hunt for valuable heirlooms known as the Lost Mistresses, objects tied to the family's history and to a powerful grandfather whose final wishes still carry enormous weight. That sends each book in a slightly different direction, but the pattern stays familiar. Someone is forced to chase the past, and love or trouble gets there first.

Money gives the series its shine, but family damage gives it its bite.

Rachael Thomas's contribution, To Blackmail a Di Sione, follows Bianca Di Sione, a successful PR boss who still carries the hurt of being used when she was younger. Her path crosses with Russian billionaire Liev Dragunov when a bracelet her grandfather wants recovered becomes the center of a dangerous bargain. The setup has everything this mini-series does well: revenge, attraction, wealth, and two people trying hard not to show where they are vulnerable.

What makes the wider series work is the mix of treasure hunt and emotional reckoning. The heirlooms matter, but mostly because of what they force the characters to confront about their family, their parents, and themselves. The romances tend to be intense rather than gentle, and the settings are luxurious, dramatic, and often far from home.

You can read Bianca's story on its own, but reading more broadly gives the Di Sione family dynamic extra weight. Expect proud characters, expensive complications, and love stories shaped by inheritance, identity, and the uncomfortable fact that the past never stays buried for long.
