Chronicles of the Ancient Sea Kings - Chronicles of the Ancient Sea Kings, #1

An epic portal fantasy unfolds. A pair of aimless Navy vets wash up in a world as baffling as the civilian one when their boat sinks off the coast of Antarctica. It's cold, but not as cold as it should be. There's no food, no water, no chapstick. Nothing but a 15th century map purporting to show the southern continent centuries before its discovery. Their hopes of a quick rescue recede with the ice as someone jacks their clothes and they find the stark land inhabited by some pretty not-chill dudes. Each encounter is a clue that raises more questions than they have time to answer in the mad scramble for survival.
And none of it matters: not the strange customs that obligated a geriatric Reverse-Eskimo to help them. The wooden museum vessels full of foul sailors. The murmurs of unrest across the seas. All they want is a boat home-any boat. But first, they must travel to the end of the known world to find out where they are.
