"A terrific novel, I heartily recommend it." -Orson Scott Card

After a solar flare accident in orbit, Travis is a hero: the first astronaut to bail out of a spacecraft and live. NASA, however, had advised against the bailout-and as punishment for violating orders, Travis is grounded on earth, never to fly again.

Then comes Starfire, an experimental spacecraft that could be capable of interstellar flight. Travis fights a desperate political battle to become a crewmember, and his go-it-alone attitude makes for some rough going. Starfire's planned maiden voyage is to land on an asteroid that is heading toward a close loop around the sun, stay long enough to explore, then return to Earth by way of a gravity boost around Venus.

But during the mission, disaster strikes again: the ship is hit by a huge solar flare and must take shelter in the shadow of the asteroid, even while falling ever closer to the sun. The aim of the mission now becomes desperate survival...
