In my previous review for Deception's Princess, I did mention Frienser's writing's lack of completely amazing qualities, but I have returned to finish off the story of Helen of Sparta! You might wish to read Nobody's Princess before proceeding to read this review.
Helen, hearing of Prince Jason's voyage to seek the legendary Golden Fleece, has disguised herself as a boy named Glaucus, and she and her friend Milo, a former slave, are sailing to Iolkos, where the Argo is supposed to be setting off from. They get work as weapons-bearers for a hero named Iolaus, and soon begin their adventure. But it's not nearly as easy as they had hoped--Helen has to avoid her older brothers, Castor and Polydeucus, lest they should get a good look in and recognize her for who she really is. On top of that, Helen's growing up, and passing as a boy becomes harder and harder with each day. As if that wasn't bad enough, she gets caught up in a horrible love triangle--she has fallen for a beautiful weapons-bearer named Hylas, who loves his master Herakles, who loves Helen's boy identity. More and more people are taken into Helen and Milo's confidence, and the secret is bound to come out soon. Some characters from Nobody's Princess reappear, such as the hero Iolaus and the famous Athenian king Theseus, along with Helen's family, and new characters are introduced, including the Argonauts, mad Princess Medea of Colchis, and the unfortunate Athenian guard Telys--and of course Menelaus, the man who will become Helen's husband, enters the picture near the end.
