The Chosen Ones

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?
