It took some shuffling and resizing to fit everything without overlaps and I think it still looks kind of lopsided (which is the reason i didn't implement it originally) but the update is on it's way
The only way to avoid the lopsidedness would be to display some fallback (not very useful) or make the cards for books with series information larger than others (also not much better

). Chime in if you have any ideas to avoid the list looking lopsided for books without series info or think that differing card sizes ar a-okay
