Everything that has a beginning has an end

Two more will complete opus (much later) the rest of the story ... and two others, will enlighten us about its genesis.
No vague resemblance to a certain cinematic trilogy in three and six (and ultimately not new) shutters ... or not.

A detail of strength, even Asimov takes us beautifully in his galactic universe.

The Mulet, the mutant psychic powers unsuspected, completes his quest for the second Foundation and its fight against its "Psychologists" in a well-crafted plot.

Arkady, a direct descendant of the Darrell family, takes us in a incredible journey through the galaxy.
Twists of twists, the characters so that readers no longer know where to turn. Who is lying? Who plays with whom? That manipulates? Who is handled "without the knowledge of his own free will"?

Asimov gives us in this opus intrigue the most successful of his trilogy.

Volumes 4 and 5 waiting for me.
