Summary
In her second summer at camp, Andie faces: people being awful about her little brother, one of her older brothers being awful to her friend (if you can call that what Polyphemus is doing), having to face yet another adventure to save camp, oh, and realising she's into girls.
Or: the book 2 re-write with a fem!Percy while in the background, Sally Jackson has now slowly become aware of being the Roman form of Amphitrite - and so have others.

Summary
Andie (well, Andromeda) Jackson is just a mostly-normal, dyslexic ADHD kid with maybe an unusually easy time in Latin class. Then, she ends up vaporizing her pre-Algebra teacher, her best friend turns out to have hooves, her mom gets dissolved into golden light after a chase by what's apparently the minotaur, and that's before she gets accused of having stolen the most powerful weapon in the world and having to get it back...
Or: A Book 1 re-write featuring fem!Percy and in the background a Sally Jackson who's kind of, sort of, the Roman form of Amphitrite, not that she knows that.

Shortly afterwards, he left Paris.
Nine months later, William Gilgamesh Clay was born.Or: Agatha as a teenage mother.

Summary
“Speak plainly, Mother.”
“Very well.” Setting the final placemat down, she looked up at her daughter. “I have been trying to respect Enid’s privacy, but I see now that I have also overestimated your deduction abilities.”
Thing’s hasty retreat from the utensil box in the center of the table and subsequent scampering across the floor was made all the more pronounced by Wednesday’s heated silence. Just as she drew in a sharp breath, though, Morticia carried on.
“The Sinclairs have five children, with the appetites of growing werewolves.” Morticia turned back to the cabinet. “And they are not financially cursed in the way we are.”
--
Morticia opens Wednesday's eyes after she embarrasses Enid for being hungry all the time
