Fairy Fantasy Featuring Finn

At the moment, I'm alternating between two modern fantasy trilogies that focus on changeling lore with supporting characters named "Finn". This is in part because reading the books in a series contiguously feels slightly excessive. But in this case, there's still a brief moment in th first few minutes of the new book in one series that makes me miss the feel of the previous series. It's because of those similarities that highlight the differences. But nah. Both are great.

Also! I just saw "Fantastic Beasts: The Crimes of Grindelwald", and I have to assume that the first part of the title is in reference to Eddie Redmayne and Ezra Miller. Incidentally, Jamie Campbell-Bower plays a younger version of Johnny Depp's character, which is what I erroneously assumed that he was doing when I walked in late to the cinema for a showing of "Sweeney Todd".

Bonus Question!
