Marshall is invited to a ball in the Nightosphere and Fionna wants in. However, when she's there, she's caught up in a sinister plan that could endanger all the occupants in the land of Aaa.

"I live off of pain, anger, blood, and sex; please, honey, take your pick." Fionna didn't know what to expect when she walked into the bar that night, but it certainly wasn't this. Modern AU. Extreme adventuring. Fiolee.

AU: Fionna expected adventure, craved it even, when she left home. She just didn't bargain for what happened once she was out on her own. At first she thought being a maid on an airship was tough, but then she had to go and get captured by pirates. None of this would have happened if they'd just let her carry her sword with her. Fiolee and established Finnceline.

Story inspired by the titular song. Fionna finds the lyrics hidden in the treehouse, written down decades before by Marshall for some long-forgotten reason, and asks the Vampire King what they are. Sadfluff, sort of. Kinda Onesided!MarshallxFionna too, but really I'm just giving the whole thing away now. More explanation in the author's note after you read. Mild cursing.

Fionna has never had good luck with men. That's why she has sworn to never be involved in another romantic relationship. Then again, who can deny a king? [credit for cover image: yami]

Fionna is a 3rd year college student studying at LIU with her best friend, Cali-Kealani (Cake for short.) One month ago, she met an intriguing bass player while waiting in the subway, and he's been on her mind ever since. But New York is a big city, and she doesn't even know his name. Will they ever meet again? [AU Fiolee inspired by song of the same name. T for sexual references]

Fionna hates her freckles. Marshall-lee think she should be grateful that she knows she has freckles. What will happen after Marshall makes the adventuress describe how he looks to her? And then accidentally tells her how beautiful she is to him? Because after all, Fionna's in love with Gumball. Isn't she? ( Rated M for lemon in later chapters, cursing and adult humor.)

It's nasty, falling in love with a Vampire King - but Fionna went and did it anyways. A story following the hero as she grows up and falls in love with the hottest vampire dude around. Fiolee

A tale of courting, confusion, conflict, corniness, and...tea parties? Marshall Lee x Prince Gumball x Fionna

Neither of them want to share the pretty blonde girl with the bunny hat. They will never be friends, but tonight, just this once, they'll work together. It is, after all, a special day. Marshall/Fionna/Gumball lemon.

Love is both ever-changing, shifting and fluid, yet remains static, fixed and constant. This is an exploration of Fionna and the complicated relationships she maintains with Marshall Lee, Prince B Gumball and the Flame Prince. Written in a style of ramblings, one-shots and musings connected by a thread of a narrative. Rated M for future Lemons.

The University of Admirable Academic Achievement is a highly respected college. It has five of the top students in the country. They excel in their studies and after high school they all became shoo-ins. These five students, unique in ability, are the prodigies of the University. Let's see how this plays out. Rated M for mature content. No flames please! Fiolee and other pairings.

"peter pan" ends on a sour note. —marshall lee/fionna
