In this Hugo-nominated novel, an alien walks into a museum and asks if he can see a paleontologist. But the arachnid ET hasn't come aboard a rowboat with the Pope and Stephen Hawking (although His Holiness does request an audience later). Landing at the Royal Ontario Museum in Toronto, the spacefarer, Hollus, asks to compare notes on mass extinctions with resident dino-scientist Thomas Jericho.

While J. Robert Oppenheimer and his Manhattan Project team struggle to develop the A-bomb, Edward Teller wants something even more devastating: a weapon based on nuclear fusion - the mechanism that powers the sun. But Teller’s research leads to a terrifying discovery: by the year 2030, the sun will eject its outermost layer, destroying the entire inner solar system - including Earth. After the war ends, Oppenheimer’s physicists combine forces with Albert Einstein, computing pioneer John von Neumann, and rocket designer Wernher von Braun.  

Caitlin Decter is young, pretty, feisty, a genius at math - and blind. Still, she can surf the net with the best of them, following its complex paths clearly in her mind. But Caitlin's brain long ago co-opted her primary visual cortex to help her navigate online. So when she receives an implant to restore her sight, instead of seeing reality, the landscape of the World Wide Web explodes into her consciousness, spreading out all around her in a riot of colors and shapes.

Neanderthals have developed a radically different civilization on a parallel Earth. A Neanderthal physicist, Ponter Boddit, accidentally passes from his universe into a Canadian underground research facility. Fortunately, a team of human scientists, including expert paleo-anthropologist Mary Vaughan, promptly identifies and warmly receives Ponter. Solving the language problem and much else is a mini-computer, called a Companion, implanted in the brain of every Neanderthal. But it can't help his fellow scientist back in his world, Adikor Huld, when the authorities charge Adikor with his murder.
