If you read the second book, it's basically Julia's book. She's basically as smart as Alice is....so she goes crazy not being able to understand why she didn't get into Brakebills but, Quentin, who's a slacker got in. In the book it's explained that Julia was smart as fukk but, didn't believe in the magic stories she and Quentin read as kids anymore so she thought the test questions were silly and stupid whereas Quentin was like a Star Wars nerd at a Jedi academy. So Julia went crazy after knowing magic was real but, she was rejected. Went to every shady alley and hangout spot to learn what she could about magic
eventually she blows past all the wannabe magicians and fakers and finds a group of real underground witches. They chilling in France, just smoking weed and doing magic all day. She gets close to everybody. Finally feels like she belongs. Finds a family. Happiness. Quentin was in Brakebills now and he kinda brushed her off when she came begging him to help her get into Brakebills after she failed the test. So finding this group helped her get over not being chosen for the school. For like 80 pages, they're preparing to summon this goddess and everybody at the house can't wait. This goddess is like the Athena or Aphrodite of magic. It essentially showed that despite her crew being smart, they weren't formally trained like the Brakebills students so they were calling up spirits and demons they had no business dealing with. Because the wholetime the Fox was listening instead
Sick fukk came through like
shyt was way more graphic in the book. Dude murdered everybody she had just gotten close to. Raped her friend, then raped her and came inside her too
IIRC, that's how she lost her soul in the books. Something about his essence being in her body changing her permanently. Shorty had every right to wanna kill that thing.
