1798. Three people, two brutal murders, one promise.

We're following in the footsteps of the Academy of the Lynx, the first Scientific Society in Europe, whose library was lost for centuries. Golo Eck is on its trail, heading for Holland; his friend Fergus tracks another part of it in Ireland, where he becomes embroiled in the Irish rebellion against English rule, including the very bloody Battle of New Ross.

When Golo disappears during a shipwreck, his ward Ruan is left to fend for himself, a stranger in a strange land.

And then there is Greta, courageous messenger for the United Irish, who links all the differing strands together as we approach the final explosive conclusion.

Award-winning author Clio Gray has written a thrilling adventure steeped in historical fact - Barberini Bees, the Melissographia, Galileo, an Aztec Khipu, all play their parts - and will keep readers gripped to the very last page.
