Space Adventures!

I just finished another Isaac Asimov book The Currents of Space,
Story of a man trying to remember who he is and the great danger he came to warn the planet about.
Another great space mystery, whodunit, with many characters playing detective.
Great visuals of a layered society with literal upper and lower classes, rich lavish city above in bright lights and peasants below in the shadows.

The follows up my previous read of Pebble in the Sky.
A man travels through time into the future, is subject to an experiment that gives him special mental powers, must adjust to a futuristic radioactive earth, must avoid being put to death for being too old, and also race the clock to save the galaxy!
Humanity has spread out across millions of planets and forgotten its origin, Earth, a poor isolated backwater planet with its population not even regarded as human anymore.

Both fun scifi stories from the library, I sure appreciate free reading.
