"Fionna and Cake" is a fan-fiction book written by the Ice King in the episode "Fionna and Cake." It is a book about the gender-swapped versions of the main characters in the show. Ice King forces Finn and Jake to listen to him reading it by trapping them in ice (though only Finn's head isn't encased). The book is much more romantic than the regular adventures Finn and Jake go on.
Not to be confused with the Fionna and Cake Omnibus.
On the cover it says "Fionna and Cake." The cover also shows Fionna and Ice King kissing. It appears to be written in some sort of binder and has no colors.
