Fire hearts (ghost rider x oc)

(Can't give so much info but, ok.)
Roseanne wasn't normal, she was born a ghost rider so she wasn't human.
Johnny blaze wasn't either but he wasn't born a ghost rider, he is possessed. After a fight now with her ex-boyfriend, Roseanne leaves and bumps into Johnny. (That's all the info I can give you, just read the book )
