I haven't read this one yet, but I tend to want to vote for BFFs. Since finishing the Raven Cycle, I am fonder than ever about books that are just about bros being bros. All I can think about for the next Star Wars movie (for instance!) is how much I want to see Poe and Rey and Finn flying all around space having BFF adventures. (Since I consider it unlikely in the extreme that Poe and Finn will kiss, which would be swell.)

Anyway! I have it out from the library! Soon lots of Rhy for me to enjoy!
