Isotta is not your average creature of the night. After being abandoned by her family in the forest as a young girl, she is rescued by Gerta, a lonely vampire in need of a companion. Over the next few hundred years, the two of them, along with Gerta's cousin, Aloiki, see the world, adapting and living according to the times. However, like Gerta before her, Isotta eventually finds herself wanting more than her vampire life has to offer. But when they eventually end up in the present day and as blood supplies begin to dwindle, she finds hope as she falls in love with a human. Can she resist the urge to bite him or will she forever make him hers?

Young Forever is the story of a girl who became a vampire but now wants to live a normal life. As normal as a vampire can, at least.
