About This Book
The chilly splash of ocean water surrounds the small Water Bug as it dives deeper and deeper, lit only by eerie glowing creatures in the dark. Andrew, Judy, and Thudd feel the hum of the engine slow—then stop—right above the ocean's deepest abyss. Now, with no power and shadows all around, their adventure turns into a race to stay alive in the mysterious depths.
