So for those of you looking for a better idea of the Geography as you read, here's a rough idea of where the cities of Mycenae, Athens, and Sparta were, in relation to one another, and the kingdom of Pirithous's people, the Lapiths, in the far north of Thessaly -- so far north, his home isn't even within the bounds of the map!
This map was published in the 1700s, and drawn by a Guillaume Delisle. I just edited and cropped it a little bit in order to make the place names that mattered to my novel more apparent in the image. (Greece is crowded!) If you're curious, you can find the original image on wikimedia commons, along with a little bit more information about the map.
And if you'd like a bigger picture of Greece -- with Thessaly included, I also highlighted the relevant places on this 1903 map (slightly edited for size and readability by me, via Project Gutenberg and The Atlas of Ancient and Classical Geography by Samuel Butler.) You'll definitely want to click to embiggen and view it full size.
Long before she ran away with Paris to Troy, Helen of Sparta was haunted by nightmares of a burning city under siege. These dreams foretold impending war—a war that only Helen has the power to avert. To do so, she must defy her family and betray her betrothed by fleeing the palace in the dead of night. In need of protection, she finds shelter and comfort in the arms of Theseus, son of Poseidon. With Theseus at her side, she believes she can escape her destiny. But at every turn, new dangers—violence, betrayal, extortion, threat of war—thwart Helen’s plans and bar her path. Still, she refuses to bend to the will of the gods.
A new take on an ancient myth, Helen of Sparta is the story of one woman determined to decide her own fate.
