From the publishers website:
In the high peaks that stretch to the floor of heaven, amid howling winds and engulfing blizzards, lurk mysteries that have waited since the dawn of time. Labyrinths of a lost civilization, now crumbling and almost deserted but still home to treasures and dangers. The mountain stronghold of the Halizons, as distrustful of strangers as their sister tribe the Amazons. Mechanical marvels built to plumb the depths of the cosmos. The fortress where Boreas, once lord of all this land, has been trapped by the forces of darkness that are working to conquer all.
Find the keys to unlock a vault that has lain unopened for millennia, sealed with curses that even the gods fear. Seek out the last of the Argonauts and enlist him in your cause. Fight a pitched battle on an inland sea against brutal raiders who will give no quarter. Twist time in a loop and steal from the messenger of Olympus. Avenge your brother’s death. Raise your adopted city to the heights of glory. Quiet the restless dead. Hunt mammoths and sabre-tooth tigers on the storm-blasted plains. Or visit the carnival of crossed destinies and learn why gods and titans have picked you out as their champion.
