A new house and a new attic hold untold mysteries for fourteen-year-old Nick, his younger brother, and new friends Mitch, Caitlin, and Vincent. The attic, it seems, was the genius Nikola Tesla's storehouse for his final invention, which needs to be assembled before use--unfortunately a garage sale scatters Tesla's individual items before Nick finds out. Now Nick must reassemble the items and keep them safe before they fall into the wrong hands.
