LONGTUSK continues the story begun in Stephen Baxter's critically acclaimed MAMMOTH. The second novel of a trilogy, it takes the story that spans millions of years back to its genesis with the story of one of mammothkind's first heroes - the bull LONGTUSK, whose heroic example inspired the actions of MAMMOTH's heroine, SILVERHAIR. LONGTUSK is responsible for leading the mammoths away from the first incursion of the dreaded human hunters, taking them to safety on the Asian landmass and in so doing changing the very architecture of Earth's prehistoric geology.
