Fable Sky, the world's largest zero-pressure helium balloon, is preparing for its inaugural flight into the stratosphere-a crucial test for an ambitious new era of space tourism. After years of planning and preparation, the five-member crew ascends to 138,000 feet, breaking the high-altitude record.
Then disaster strikes.
As events unfold far below, the crew slowly realises that something is terribly wrong. Cut off from flight control and unable to comprehend what they are witnessing, they find themselves alone, adrift, and facing a desperate race against time.
With their oxygen supplies dwindling, Will, the project leader and captain, must guide his crew through the hostile stratospheric environment and find a way to descend safely.
But getting back to the ground may be the least of their problems.
BALLOON is a high-stakes thriller of survival, suspense, and catastrophe, where five people stranded above the clouds must confront an unimaginable event that has changed the world forever.
