Master of the revels / Nicole Galland.

This fast-paced sequel to the near-future adventure The Rise and Fall of D.O.DO. picks up where the original left off, as Tristan Lyons, Mel Stokes, and their fellow outcasts from the Department of Diachronic Operations (D.O.D.O.) fight to stop the powerful Irish witch Grainne from using time travel to reverse the evolution of all modern technology. Chief amongst Grainne's plots: to encrypt cataclysmic spells into Shakespeare's "cursed" play, Macbeth. When her fellow rogue agents fall victim to Grainne's schemes, Melisande Stokes is forced to send Tristan's untested, wayward sister Robin back in time to 1606 London, where Edmund Tilney, the king's Master of Revels, controls all staged performances in London. And now Grainne controls Tilney. While Robin poses as an apprentice in Shakespeare's Globe Theatre, Mel travels to the ancient Roman Empire and, with the help of double-agent Chira in Renaissance Florence, untangles the knotted threads of history while the diabolical Grainne jumps from timeline to timeline, always staying frustratingly one step ahead-or is it behind? Historical objects disappear, cities literally rise and fall, and nothing less than the fate of humanity is at stake. As Grainne sows chaos across time and space, the ragtag team of ex-D.O.D.O. agents must fix the past-in order to save the future.
