It's one I read a long time ago. I remember a few choice details:
It was about a scientific expedition surveying the death of a planet by gravitational destruction. A rogue gas giant is ripping the crust off the smaller planet as it passes before consuming it
The original expedition (somewhat far in the past of the book's setting) either crashed or couldn't take off after landing when their shuttle malfunctioned. They had to be retrieved by a second shuttle.
There were razor birds. They swarmed and tore people apart.
The second expedition (the one right before the planet's death) crashed and has to go get to the original shuttle (the one from the first expedition) before the planet dies.
They discover the ruins of an alien civilization as they're making the mad dash to the shuttle from the first expedition.
I really want to read this again, but can't seem to find it anywhere. If anyone knows what this book is, I'd really appreciate the info.
