Stolen treasure. Hidden debts. Names an empire tried to bury.

Follow Sania Qureshi, Aryssa Oluska and Inaya Al-Sayed through three investigations into the hidden legacy of empire, where recovering the evidence means recovering the lives and names behind it.

This bundle contains three paperback books by Rose Sandy: Sapphire Conspiracy, The Paper Empire and The Queen's Labyrinth, Books 4–6 of the Daughters of Empire series.

Book 4: Sapphire Conspiracy

A 183-carat star sapphire resurfaces with a history Aryssa Oluska knows from her own family. At a London auction preview, she poses as buyer's agent Dina Fadel to find the Azure Heart. When one of three pre-qualified bidders is found dead, Inaya fears the others could be next.

Sania opens the stone's hidden data and uncovers fourteen sets of coordinates across six countries, information three mining houses want buried. With the sale moved to a private treaty at an Alpine estate under cover of the Collector's Ball, the team must reach the sapphire before its secrets disappear into private hands.

Book 5: The Paper Empire

Hours before a restricted room at Cambridge's University Library burns, Aryssa removes four grey ledgers. Inside is evidence that money owed to the people of an empire was recast as debt owed by their own colonies. Eleven treasuries are still paying a family settlement, and eleven names wait in a pencilled margin.

Sania follows the money through Zurich, Zug and Lugano while the secrets she must keep strain her marriage to Interpol's Eric Nenton. Aryssa searches archives in Belfast and Nairobi, and Inaya becomes Layla Farouk to reach the authenticators. Behind the records stands Dame Cordelia Pellatt, whose influence extends to the boards deciding who may read them. Her hired man, Raith Hawthorne, is already one step ahead.

Book 6: The Queen's Labyrinth

A deliberately set fire at Thornwick Estate in Norfolk exposes a Victorian iron door. An emergency heritage order will seal the site on Christmas Day, a demolition permit is already filed, and the Special Cases Directorate has seventy-two hours to uncover what lies behind it.

Inaya enters the monitored house as architectural historian Dr. Nour Abdelrahman. Sania works the wires from a village van, while Aryssa takes an old servant passage underground. Their target is the master record of a secret circle of colonial officials who intercepted wages and pensions owed to labourers, seamen and soldiers' families, then buried their petitions. Every name in the ledger represents someone still owed.
