A sequel to Frog Whistle Mine. Tony Hogan-White now lives in Christchurch, with his Mum and her geologist partner. Tony and his new stepfather have a holiday bonding trip back to Fox Glacier, where another exciting adventure ensues. Combines ecothemes, NZ geology and flora and fauna, global warming and the foibles of human nature. Will be supported by superbly detailed teacher's notes. Written to appeal to the 9-12 readership successfully developed with his earlier books, with an increased print run. Special features will include additional material about glaciation and keas at the back of the book.
