Effie and her gifted friends—Raven, Maximillian, Lexy, and Wolf—embark on another adventure to save the world from the evil Diberi. The second book in the magical Worldquake series, that’s “tailor-made for Harry Potter’s fans” (Kirkus Reviews), will leave you utterly entranced. Effie Truelove has just been expelled from magic class and now she can’t even get back to the Otherworld—the place she most loves and where she feels she belongs. If she can find a copy of The Chosen Ones by Laurel Wilde to give her father then she might be able to fix everything. The only problem is that there are suddenly no copies of the book anywhere, because Albion Freake, the richest man in the world, is paying for them to be destroyed so that he can own the single-volume limited edition that publisher Skylurian Midzhar is making for him. Raven Wilde’s witch’s intuition tells her there’s something suspicious about Skykurian’s plan, but she’s not sure what it is. And Maximilian has somehow managed to go missing deep in Napoleonic Europe. Will the five friends from Dragon’s Green—Effie, Raven, Maximilian, Lexy, and Wolf—be able to combine their skills again to save the world from the Diberi? And can they get away from Terrence Deer-Hart, the children’s author who seems a bit too interested in Effie’s life?

Effie, Wolf, Raven, and Max are faced with their most challenging adventure yet in the third installment of the magical Worldquake series, which Kirkus Reviews calls “tailor-made for Harry Potter’s fans.” Effie Truelove and her school friends Lexy, Wolf, Maximilian, and Raven must put their magical skills to the test. The Diberi, a corrupt organization intent on destroying the world, has returned and has something sinister planned at Midwinter. But during a visit to the Otherworld, Effie is mistaken and imprisoned for being a galloglass—a dangerous, selfish islander. Meanwhile, Lexy is threatened by the vile professor Jupiter Peacock and Wolf embarks on a perilous journey to find his missing sister. And back at school, Neptune the cat is bored. He’s used to lording over the other stray cats, but they’ve all mysteriously vanished. Where could they be—and how will he find them? Can Effie and her friends reunite before their universe ceases to exist?
