Saturn Return in Fiction: Maxi Amberville in I'll Take Manhattan
Okay, wacky idea, but I figured it might be a good one to mention characters who relate to this topic.
The setup: Maxi Amberville is 29 years old at the start of the novel. She's spent almost her entire life as a charming party girl, the sort who gets voted class president just before she gets expelled. She's held one job in her life as an intern for one of her father's magazines (he has a magazine publishing company), which she was a total dilettante about ("Lunch! Three free hours to shop!") until a hunky fellow named Rocco was hired. Maxi immediately became the world's most helpful assistant to him, and later ended up marrying him/having his kid before the marriage blew up after about a year. Since then she's been divorced two more times after impulsively marrying two other blokes. Her second husband, known as Bad Dennis Brady, well...it's a good thing he inherited money, because he had no interests other than boating, gambling, and boinking. Maxi got fed up with his lack of ambition and then ended up marrying a guy with ambition...only he was kind of nuts and his ambition had more to do with the past than anything else. So, basically, she's gotten married a few times, raised a kid, and shopped a lot. Her goal in life is the Search for the Ultimate Fun.
Then Maxi finds out that her evil uncle Cutter has just married her widowed mother (yes, this is partly a retelling of Hamlet, but with less deaths) and taken over the family company. Which he means to destroy. None of Toby Amberville's kids showed interest in taking over the biz in the first place (Maxi was partying, Justin was roaming the world, and Toby is legally blind), so you'd think nobody would care if he starts cutting corners, right? Well, Maxi, who was her daddy's favorite, pitches a fit and demands control of one of the to-be-axed magazines. She picks "Buttons and Bows", the first magazine her dad ever founded, on a whim. It seems like a pretty stupid whim when she goes down to the place and finds it pretty well dead already.
So Maxi decides to create a new magazine on top of the old one. She buys every magazine she can find on the stands, reads them all, and gets vastly furious with the "shame, shame, you're not good enough" messages of every dang women's magazine out there. (AMEN TO THAT.) Her magazine idea then becomes "B&B, the magazine that loves you." It's all about fun. Reusing stuff in your closet, amusing celebrity confessionals, and no shaming and guilting! Much to her surprise, Maxi finds that the Ultimate Fun is...work. Who knew?
Maxi's birthday isn't outright stated in the book, but it's indicated to be in August. No way in hell is she a Virgo, so clearly she's a showboat Leo kinda girl.
