The second book in the quirky and enchanting Darwen Arkwright series! Eleven-year-old Darwen Arkwright's life changed forever when he first set foot in Silbrica, the wondrous and magical world beyond the mirror. Now, he and his friends Rich and Alexandra--the Peregrine Pact--must journey to Costa Rica to save a boy who's been stolen by the Insidious Bleck, a giant tentacled creature that leaves destruction in its wake. But what at first seemed to be a single kidnapping turns out to be an elaborate conspiracy that threatens the very future of our world. And this time, old allies can't be trusted, and the danger runs deeper than Darwen could have ever imagined. Kirkus Reviewscalled the first Darwen book "Brilliant!" and we think you'll agree. It's a completely modern take on the kind of fantasy that has delighted middle-grade readers for generations.
