Then the attacks continue in London – targeting those connected with the Fae-dragon peace treaty. Irene knows she must stop the plot before the treaty fails. Or someone dies. But when Irene and friends are trapped underground, in a secret archive, things don’t look so good. Then an old enemy demands vengeance, and a shocking secret is revealed. Can Irene really seize victory from chaos?
