Book excerpt: A classic story of imagination, friendship, rock bands and high-speed helicopter chases. For fans of Ivy & Bean, Judy Moody or Nate the Great. Everyone's favorite odd couple is back. Our heroine, Renata Wolfman (Wolfie) does everything by herself. Friends just get in the way, and she only has time for facts and reading. But friendship finds her in the form of Livingston Flott (Fly), the slightly weird and wordy boy from next door. This time, Fly has convinced Wolfie to join him in his one-man band. Before they know it, they're playing live onstage in front of a stadium of screaming fans. But these fans are about to get out of control--and Wolfie and Fly have to make a daring escape! Even though Wolfie thinks she'd rather be at home reading by herself, playing the drums in a rock band is actually pretty fun. Maybe there is something to this friend thing...
