Everything centred on Ottery-St-Catchpole, as best she could determine. The Weasleys and Lovegoods both were all over Harry's life. You didn't see it with Luna and her father until you looked closely. What did the Weasleys know about the Deathly Hallows? Not a thing. Hermione had been told by Genius they were an urgent study, and that only Xenophilius knew about them.
What could the Weasleys do to counteract the Daily Prophet - the mouthpiece of the Death Eater faction in the Ministry? Nothing. Arthur would just lose his job, and the Umbridges and McNairs would redouble their efforts. Rita Skeeter would be given more money and an even freer hand to destroy not only Harry, but the Weasley family alongside them.
As for the Burrow, it held the key to Sirius Black's freedom. She congratulated herself on guessing he was the key to helping Harry. Then again, she blushed. His "obviously heroic name," after all, was just his name. If you're going to do this like a silly girl, she thought, you may as well give up now.
Her parents felt like the entire Granger family had crossed the Rubicon already. When she asked them to drive to Devon over a weekend, they went along. They gave themselves plenty of time, and it was a pleasant trip. Sure enough, when they got to a crossroad with a sign pointing to Ottery-St-Catchpole, her parents could not see it.
On a whim, she asked her father to stop and go back. When he arrived at the crossroads, she had him stop. She touched his arm and pointed at the sign. He looked over it and then snapped back to stare at the intersection. "Well, I'll be," he said.
It read "Ottery St Catchpole - 5 Leagues."
"Leagues!" said Hermione out loud. "Good Lord. I wonder how many furlongs that is."
At that, the sign changed to read "Ottery St Catchpole - 120 Furlongs."
Hermione was in no mood to actually meet (in her head, confront) anyone from the books there. Because both the Lovegoods and Weasleys were purebloods, and because the sign was invisible to Muggles, she feared the worst. The town, however, had clearly had Muggleborn visit with their parent before, and everyone was polite. When Hermione asked what the interesting buildings around were, they got clear directions - well, clear for Wizarding Britain - to both the Burrow and the Rook.
They drove near enough to see the outlines of both buildings. After that, Hermione gratefully said they could go home. It was yet more confirmation that what she thought of as "the book world" was nothing of the sort. It was merely the world.
