Agatha Parrot and the Heart of Mud

Martha's mom has banned her from playing soccer, and it's up to Agatha Parrot to find a way to get her back into the game. Meanwhile, Agatha's big brother, James, receives an email from an unknown girl, and Agatha intervenes to start a correspondence on his behalf. When she discovers the girl's love of spelling might hold the secret to helping Martha get permission to play soccer, the emails turn very warm indeed. Several forged emails--and a few spelling tests--later, will Martha get to play in the big game? And what will happen when Agatha's unknowing correspondent meets the real James?
