Cleopatra's Poison

No one has ever found Cleopatra's tomb. What if that's because it was never meant to be found?On a windswept headland above the Mediterranean, archaeologist Sarah Chen uncovers an intact burial chamber: gold, a sarcophagus, a mummy. The find of the century. Too perfect. A specialist in detecting forgeries, Sarah sees a decoy-and, behind it, what the queen sealed away for eternity. Not a treasure, but a laboratory.
Cleopatra was a chemist of genius, and beneath the sea she hid a living secret that the pharmaceutical industry will do anything to patent. When an impossible "DNA match" appears to cover the theft, Sarah realizes this dig was never about science. The seal is broken. The chamber is flooding. Seventy-two hours remain before the queen's legacy is lost-or falls into the wrong hands. Two women, two thousand years apart, bound by a single oath: to decide who owns the past.
Cleopatra's Poison braids Ptolemaic Egypt with the twenty-first-century race for patents where the last queen of Egypt's greatest secret isn't political. It's pharmaceutical-and today it's worth billions.
