A Thousand Ships

Helena Jackson's life is fine, really. Sure, she hates her boarding school right in the city, her mom is married to an abusive asshole, her dad is some flake, and she and her twin brother are for some reason not allowed to ever go to the same school, but really, it's fine. And then Percy gets expelled, again, his best friend turns out to be a goat, their mom gets kidnapped, and her flake of a dad is actually a god. Oh, right, and apparently they're now the lead suspects in the case of Zeus' bruised ego. But still, her life is fine, really.
