Intrigue and danger surround two young boys and their dogs as they seek to unravel a castle mystery.

A nearly disastrous car wreck in Germany launches twelve-year-old Gabriel Zanadu, Alexander, his fourteen year-old brother, and their two dogs, Thunder and Lightning, into a sinister adventure near the famous German castle, Neuschwanstein. Unexplained eavesdropping, death threats, and heart-pumping danger drag Gabe, Alex, and the dogs into the clutches of a little-known foreign terrorist network. After they are kidnapped by the terrorist, and even though they are scraped, bruised, and battered, Gabe and Alex use what they've learned from their military dad and home-schooling mom to clash with the criminals.

Fear, pain, and failure drive the boys to tears as they struggle to free themselves from their kidnapper’s grasp. The usual brotherly fights must take a backseat as the boys and dogs scramble to break free and escape from their enemies in the dark, cramped spaces of an underground battlefield. Hiding, out-of-breath chases, and deadly force all come into play. Find out how Gabe, Alex, Thunder, and Lightning survive and escape.
