In Volume I of the Madison Adventures, Mike Madison, Intrepid Explorer, Mike, his dad, and their growing group of friends tackle a century-old mystery of an infamous train robber, a missing fortune in gold, a voodoo curse, and a high-tech terrorist plot. That would be enough adventure for most families, but new friends and new neighbors bring more intrigue to the Madison clan. Mike's new classmate, Kathryn Harris, is hiding a heart-breaking secret about her father, FBI agent Thomas Harris-and Mike can't resist when she asks for help. The new neighbors, Joyce and Jim Mills, have very quirky personalities. Jim seems to be able to read minds and Joyce has this troubling, even frightening habit of "zoning out" as Mike's mom, Melanie, describes it. Worried that the Mills might be more than just simply annoying, Dan calls on the family's network of friends-friends with unique, diverse skills. Former covert operative & National Security advisor, Steve Jones, computer geeks, Paul and Liz King, and country lawyer, Del Reese all team up with the Madisons to confront these new mysteries. The danger is real as the group encounters rogue FBI agents, a mad scientist, greedy government officials, professional assassins-and it requires all of the group's considerable skills to keep everyone safe.
