Two female titans — perfectly matched in guts, guile, and political genius.

Elizabeth, queen of England, has taken on the mighty Spanish Armada and, in a stunning sea battle, vanquished it. But her troubles are far from over. Just across the western channel, her colony Ireland is embroiled in seething rebellion, with the island's fierce, untamed clan chieftains and their "wild Irish" followers refusing to bow to their English oppressors.

Grace O'Malley — notorious pirate, gunrunner, and "Mother of the Irish Rebellion" — is at the heart of the conflict. For years, she has fought against the English stranglehold on her beloved country. At the height of the uprising Grace takes an outrageous risk, sailing up the Thames to London for a face-to-face showdown with her nemesis, the queen of England.

In this "enthralling historical fiction" (Publishers Weekly), Robin Maxwell masterfully brings to life these strong and pugnacious women in order to tell the little-known but crucial saga of Elizabeth's Irish war.
