Okay, with my renewed interest in many things Caltech, I learned about this book when I was looking at some Wikipedia page that referenced popular culture that included something about Caltech. I'll admit I knew about the big ones, Real Genius and the TV show Numb3rs. Books, however, I knew less so, with the exception of Contact.
This one was a new one for me, and, oh boy, am I glad I picked it up. I've enjoyed Sanford
book I've read so far, though I am deliberately avoiding the Prey series, because, eh, not really interested in those, more interested in the Virgil Flowers humour.
You can tell the Sanford parts reading Saturn Run, said definitely shows through. The characters in Saturn Run have a similar flavor. That the book starts at Tech doesn't hurt, either.
Basic premise: fluffy pretty-boy Caltech grad student is the first to spot a decelerating object near Saturn, and (because objects don't decelerate naturally in space), all hell^H^H^H^Hconspiracy theories break loose. Pretty much the US and China do a mad dash to Saturn to see what the hell this thing is. If not for the space race going on, we'd get there in a unified fashion, but, well, people.
The science in the book is lots of fun, and, much like The Martian, believable (which, I gather in the point, Ctein being Sanford's science guy). If you're not a fan of the science stuff, the long winded technical parts might suck for you. I thoroughly enjoyed them, and strongly recommend this book to my geeky friends who want a fun read. Non-geeky friends, read fast through those part maybe?
If you do read the book, note how quickly you discover that the fluffy guy really isn't so fluffy. Fun stuff.
