"Jim?" Hermione tilts her head. She knows two Jims that are Captains of a certain Starfleet Ship. And the interests that Spock describes matches some of the things that both Jims are also interested in.

So she just has to equate what they might like, plus add the factor that this is an older version, and she could make an educated guess on what he would like.

Hermione reaches into her beaded bag, and pulls out a book (that is larger than the bag itself). The title is "The Tales of Beedle the Bard". "This is a Wizarding classic. And is full of puzzles, adventure, and learning new stories. I think he would enjoy it. A lot."
