Trapped in the Tunnel - Audiobook

Indiana, 1987. Gary Fitzpatrick refuses to let his wooden leg slow him down. And though his dream of becoming a firefighter has gone up in smoke, the young cancer survivor still loves playing alongside his two supportive brothers. But after their mom's fear of shady strangers in an abandoned house next door threatens to uproot their world, he vows to prove the neighborhood is perfectly safe.
As he starts making plans, the thirteen-year-old is surprised when an eccentric antique dealer asks for help finding the owner of a clock. And when the odd man hands over a map with lines interconnecting the homes in the area, Gary suspects it's showing old underground passageways and sees an opportunity to solve the puzzle.
Deciding not to tell their parents of the mysterious plot, will Gary and his siblings' choices cost them their lives?
