Isaac Asimov’s Robots and Aliens Book 3: Intruder by Robert Thurston

I wasn’t sure what to expect from Timothy Zahn after the first book in this series. Johnny, the main character from the first book, now has three sons. The eldest at 27 is involved in politics, just like Johnny. The two other sons are a pair of twins, one which becomes a Cobra. I was hoping that there would be more action, but for the first third of the book I was fairly disappointed. It consisted mostly of political ramblings concerning a very controversial offer that one of the Troft trading partners proposed. They had identified a world near Troft space that was considered a significant threat. If the Cobras could neutralize this threat, the Trofts were willing to give the colony five new worlds. (more…)

I came across a recommendation for Tau Zero by Poul Anderson on a top 10 list of science fiction novels. I was a bit intrigued because I recognized all of the authors on the list except this one. I did a little bit of research and found that this novel was more of “hard” science fiction. I wasn’t sure exactly what to except, and after just a few chapters I was pleasantly surprised.

A group of 25 male and 25 female scientists are selected to go on an interstellar colonization mission. Their ship, the Lenora Christine, is equipped with an advanced Buzzard engine. This engine is designed to feed off of hydrogen particles in its path while at the same time repelling other particles that would normally tear the ship apart at high velocities. The ship is designed to travel at near the speed of light, and relativity plays a significant role in the plot. After striking a nebulae that was a bit too dense for the Buzzard engine to redirect enough particles, the decelerator was damaged. There was no way to slow down. If they shut the Buzzard engine down to make repairs, they would be killed in minutes without the shielding. (more…)
