The Techie Twins Adventures: The Signal

By Terrence Pulliam

Something is pinging in Echo City - damaged, corrupted, and impossible to ignore. When Ariel and Tyler track a mysterious HexCore signal to a hidden lab, they discover the truth about Hexar's origins and a secret Granny Easter has been keeping since the very beginning. But solving one mystery only opens the door to a bigger one.

Because waiting at the end of the signal are two suits. Beautiful. Advanced. Powerful. And Hexar knows exactly where they are.

The adventure is just getting started.
