Upended

When a failed experiment renders everything within a mile completely weightless, Dr. Kyle Kessler narrowly avoids joining the countless cars, buildings, and people falling into the sky.

In the aftermath, he and the other survivors are given a choice: regain their weight with time or become astronauts in the newest space program. With the wealth of weightless materials, NASA plans to build a spacecraft capable of venturing anywhere in the Solar System without gravity to hold it back.

But for this diverse and inexperienced crew, astronaut training may prove to be as dangerous as space itself. And if Kyle can't keep the truth of the failed experiment out of the wrong hands, it could destroy the only thing holding Earth together.
