by Caroline Cash

It’s . . . ALTERNATE UNIVERSE TIME! From the mind of Eisner Award–winning cartoonist Caroline Cash (PeePee PooPoo), experience all the fun of college (and none of the stress) in this giant-sized spectacular starring Princess Bubblegum and Marceline! What, do you think Ice King should get to have all the fun?! Heck nah! Fanfics are cool and all, but you know what’s even cooler? Peering into alternate universes—and Prismo’s got the perfect one in mind . . . Princess Bubblegum has just started school at Ooo University (double majoring in chemistry and princess, of course!). But between difficult roommates, overreaching bodyguards, assassination attempts, and—more importantly—a full class schedule, will Bubblegum be able to survive her first year in college?! With the help of one super-cool, super-mysterious flying vampire who she is mayybeee falling in love with, it shouldn’t be all that hard. Turns out Marceline and Bubblegum are made for each other in any universe!

This was fantastic! I haven't read the Adventure Time comics but I loved the show. Saw Caroline Cash made this one shot and knew I had to give it a try. It was incredible. Showing us an alternate reality where our favorite characters are in college. Classes, parties, and spin the bottle. Leading to a relationship we've all wanted to see more of! It's adorable. A nice little hit of romance with some on brand comedy for the series. Great book all around. Definitely recommend if you're a fan of romance or a fan of Adventure Time.

Se siente literalmente como leer un fanfic de wattpad escrito por una preadolescente con necesidad de contenido sobre su ship favorito (podría ser yo perfectamente).
Es como muy "forzado" todo, pero está bonito igual porque eso hace que se Marceline y PB se quieran y se den besos, así que yippie (como si no ocurriera en el canon, sabes JAJAJAJ).
Pero bueno en fin, la portada es preciosa (tengo otra versión) y las referencias están guays, así que cool.
Besitooos

“i wonder what my roommate will be like? will she be kind and studious like me? i hope we’ll stay up late, doing homework together. oh it’ll be lovely to have a peer to discuss geo-politics with.”

yuri exists in all princess bubblegum and marceline timelines beautiful 🙏🏼

bought this because I'm depressed and have free will. I feel slightly less depressed (and like I missed out on the college experience to save money that I'm now spending in the hopes of filling the void)
