Children of the Frost [EPUB ebook] 

A weary journey beyond the last scrub timber and straggling copses, into the heart of the Barrens where the niggard North is supposed to deny the Earth, are to be found great sweeps of forests and stretches of smiling land. But this the world is just beginning to know. The world’s explorers have known it, from time to time, but hitherto they have never returned to tell the world.
