Ark and his friends must travel deep into enemy heartland to find out what evil is planned. Awaiting them is a glittering forest of glass skyscrapers, a twisted echo of home. But the wildlife within is infinitely more dangerous... The second book in the gripping 'Ravenwood' fantasy adventure trilogy from Andrew Peters.
