"June is a brilliant but difficult girl with a gift for mechanical invention who leaves home to begin a grueling astronaut training program. Six years later, she has gained a coveted post as an engineer on a space station, but is haunted by the mystery of Inquiry, a revolutionary spacecraft powered by her beloved late uncle's fuel cells. The spacecraft went missing when June was twelve years old, and while the rest of the world has forgotten them, June alone has evidence that makes her believe the crew is still alive. She seeks out James, her uncle's former protégée, also brilliant, also difficult, who has been trying to discover why Inquiry's fuel cells failed. James and June forge an intense intellectual bond that becomes an electric attraction. But the love that develops between them as they work to solve the fuel cell's fatal flaw threatens to destroy everything they've worked so hard to create--and any chance of bringing the Inquiry crew home alive."--Provided by publisher.
