I don't actually want to read about characters in unbelievable extremity, trying to choose between sacrificing half their loved ones and sacrificing the world

Oh hey, you haven't read Tanya Huff's Keeper books (I think I lent the first one to your sister?) They are urban fantasy without the horror elements, funny instead of grim, and also the third one has two girls falling in love whilst saving the world! In a shopping mall! With mall elves!
