Klem Antrim would go to the ends of the Earth to see his father alive againโbut heโll have to travel much farther than that.
Klemโs life in picturesque Sea Scarp has just taken a turn for the worse. The car crash that killed his father knocked Klem straight out of reality, and since that day nothing in his life has seemed quite right.
Not only is Klem being followed, he keeps stumbling into invisible tunnels that snake through town. But when he peers through one tunnelโs glassy walls and catches a glimpse of his fatherโalive and wellโKlem realizes the town outside the tunnels isnโt his Sea Scarp at all. Such things arenโt possible, of course. But if Klem is losing his mind, then how has the mysterious stranger whoโs been tailing him already mapped out every invisible hole in town?
Now Klem will set out to find the one tunnel that leads to his father. But unraveling the truth behind his fatherโs death is about to unravel a much more dire truthโa truth thatโs been hidden in plain sight.
