Second Star (Star Svensdotter #1)
Classic SF. Given that I grew up in the days when the Russians (or Soviets) were a driving force, this novel felt familiar. This is basically an alternate future book, where a message from space shows that Aliens are out there and motivates the world to head outwards to greet those aliens on a more equal footing.
Star is basically a construction manager / captain of the still developing L5 community being put together by the Western alliance (US, Japan, Mexico, Canada) on a grand scale (miles long rotating habitat meant to house 1 million people? That's the definition of grand scale!). Of course, there are a lot of issues. The potential of a hostile takeover, construction delays, solar flares and, yes, aliens all make this book an entertaining read.
Amazingly for a book written 2 decades ago, the book holds up fairly well (other than the geo-political aspects). I had to go back see when it was written and was quite surprised at the date.
