Here's the blurb:
Two months since the stars fell... Two months since sixty-five thousand alien objects clenched around the Earth like a luminous fist, screaming to the heavens as the atmosphere burned them to ash. Two months since that moment of brief, bright surveillance by agents unknown. Two months of silence, while a world holds its breath. Now some half-derelict space probe, sparking fitfully past Neptune's orbit, hears a whisper from the edge of the solar system: a faint signal sweeping the cosmos like a lighthouse beam. Whatever's out there isn't talking to us. It's talking to some distant star, perhaps. Or perhaps to something closer, something en route. So who do you send to force introductions on an intelligence with motives unknown, maybe unknowable? Who do you send to meet the alien when the alien doesn't want to meet? You send a linguist with multiple personalities, her brain surgically partitioned into separate, sentient processing cores. You send a biologist so radically interfaced with machinery that he sees x-rays and tastes ultrasound, so compromised by grafts and splices he no longer feels his own flesh. You send a pacifist warrior in the faint hope she won't be needed, and the fainter one she'll do any good if she is. You send a monster to command them all, an extinct hominid predator once called vampire, recalled from the grave with the voodoo of recombinant genetics and the blood of sociopaths. And you send a synthesist—an informational topologist with half his mind gone—as an interface between here and there, a conduit through which the Dead Center might hope to understand the Bleeding Edge. You send them all to the edge of interstellar space, praying you can trust such freaks and retrofits with the fate of a world. You fear they may be more alien than the thing they've been sent to find. But you'd give anything for that to be true, if you only knew what was waiting for them...

Here's the blurb:
One night in October when he was ten years old, Tyler Dupree stood in his back yard and watched the stars go out. They all flared into brilliance at once, then disappeared, replaced by a flat, empty black barrier. He and his best friends, Jason and Diane Lawton, had seen what became known as the Big Blackout. It would shape their lives. The effect is worldwide. The sun is now a featureless disk--a heat source, rather than an astronomical object. The moon is gone, but tides remain. Not only have the world's artificial satellites fallen out of orbit, their recovered remains are pitted and aged, as though they'd been in space far longer than their known lifespans. As Tyler, Jason, and Diane grow up, space probe reveals a bizarre truth: The barrier is artificial, generated by huge alien artifacts. Time is passing faster outside the barrier than inside--more than a hundred million years per day on Earth. At this rate, the death throes of the sun are only about forty years in our future. Jason, now a promising young scientist, devotes his life to working against this slow-moving apocalypse. Diane throws herself into hedonism, marrying a sinister cult leader who's forged a new religion out of the fears of the masses. Earth sends terraforming machines to Mars to let the onrush of time do its work, turning the planet green. Next they send humans...and immediately get back an emissary with thousands of years of stories to tell about the settling of Mars. Then Earth's probes reveal that an identical barrier has appeared around Mars. Jason, desperate, seeds near space with self-replicating machines that will scatter copies of themselves outward from the sun--and report back on what they find. Life on Earth is about to get much, much stranger. At the publisher's request, this title is being sold without Digital Rights Management software (DRM) applied.
