1. if she can switch 8 letters into dear KABY, it's pretty likely its for KABY. because it can't be coincident that a guy whose name is Kaby would want the book, therefore she deduced from THAT that the book was intented for him, and not anyone else.

2. that Wind glasses only allows you to read fast, not interpret it. reading faster =/= understand it. Keep that in mind.

Eg. if you've never done biology, or chemistry and you see this: C6H12O6 + O2 + 6H2O -> 6CO2 + 12H2O You've read it, but it doesn't mean you understand it.
