If you love stories the likes of Clash of the Titans or Conan, then you will enjoy Forshanaland. Set in the Frost Lands, Pinaari travels to this wintry realm, thousands of miles away from everything he knows, to find the man who can save his homeland.
Only Pinaari gets drawn into battles with giant serpents and forest spirits, risks his life to reach the realm of the dwarfs (and a deadly encounter with the fire-wielding king), almost gets eaten by shadow-dwelling creatures, and is nearly crushed by the biggest monster of them all--the Noshaer; all of this while travelling with the hero Shasteen and his half-god friend Borl as they search for a means of defeating the behemoth beast.
A magical horn, given to the King of Oselon a hundred years ago, has the power to summon a beast of equal strength to the Noshaer and keep it at bay. The horn requires four magical coins to bring forth the Dosamoor, but the four coins have been scattered across Forshanaland. It is up to Shasteen and Borl (and Pinaari) to find the four coins, summon the Dosamoor, and keep the people of Oselon (and all of Forshanaland) from being devoured by the monster.
