About the author

Donald Moffitt

23 books27 followers
Donald Moffitt was born in Boston and now lives in rural Maine with his wife, Ann, a native of Connecticut. A former public relations executive, industrial filmmaker, and ghost­writer, he has been writing fiction on and off for more than twenty years under an assortment of pen names, including his own, chiefly espionage novels and adventure stories in international settings. His first full-length science-fiction novel and the first book of any genre to be published under his own name was The Jupiter Theft (Del Rey, 1977).

"One of the rewards of being a public relations man specializing in the technical end of large corporate accounts," he says, "was being allowed to hang around on the fringes of research being done in such widely disparate fields as computer tech­nology, high-energy physics, the manned space program, polymer chemistry, parasitology, and virology—even, on a number of happy occasions, being pressed into service as an unpaid lab assistant."

He became an enthusiastic addict of science fiction during the Golden Era, when Martians were red, Venusians green, Mercurians yellow, and "Jovian Dawn Men" always blue. He survived to see the medium become respectable and is cheered by recent signs that the fun is coming back to sf.

Kube-McDowell's eclectic trilogy finishes with more of a whimper than a bang, but Emprey provides enough philosophical and sociological ponderings to keep the reader going. The last installment concluded with Merrit Thackery making contact with an alien species that lives in the 'spindle' universe, one that parallels our 'material' one, or rather, our material one exists as a subset of theirs (whew!). While 'transported' to the spindle, Merrit finally was given the answers to the 'Founder Civilization' (e.g., who was behind the human diaspora colonies) and what destroyed it. Turns out, there is yet another alien species, the shadowy Mizari, who inhabit space fairly close to humanity's explorations and they do not like visitors. After Merrit revealed this, humanity's space explorations ceased, but a new 'war' faction emerged, who want to confront the Mizari and essentially wipe them out...

What I found most intriguing about this installment were the cultures elucidated by Kube-McDowell of the diaspora colonies, which range from matriarchies to scholarly kingdoms; unfortunately, the cultures were not fully developed here, just certain aspects that played a role in the broader story. The speculations on human nature were also fun (is humanity doomed to war, are we Janus-faced between 'protection' and 'procurable', etc.). All of this took place as humanity gears up for war amid political struggles to define what the future governance structure will look like. Decent trilogy, although I still have no idea what the Trigon Disunity is, and that is the name of the trilogy itself! 3 meandering stars.

Overall I enjoyed the third and last installment of Kube-McDowell's Trigon Disunity. The continued focus on politics and technology is very good space opera, indeed. The 'super powerful' space entity trope fits well into the genre as well. The only negative I have with the book is I feel it needed an epilogue.

The last Mazari attack was long ago but it was so devastating that Defense Director Wells in the United Worlds has worried himself into a monomaniacal paranoia about them. Triad is the new super weapon that uses the energy of the spindle (a vast source of vacuum multidimensional energy) and the deployment of three of these weapons occupies most of the factional government’s time. Some planets want it used while others are adamant that they shouldn’t poke the bear. In a totally political move Janell Surjata has been made Chancellor of the government but is being manipulated by both factions. Into the mix comes the legendary spacer Merrett Thackery, thought dead, who steals his old ship and heads into Mizari space. The bear duly appears and the D’shanna that fled uptime through the spindle may be needed… Michael P. Kube-McDowell closes out his Trigon Disunity trilogy with a breathtaking race to avoid war. Note: You will need to have read Emprise and Enigma to fully appreciate this book.

A great finish to the trilogy. Quite heavy on the politics side of the expanding human collective, not to everyone's taste but worked well for me. A little space opera towards the end for those who like that sort of thing!

Though slower to get rolling than the first two installments, this was a philosophically satisfying closing to the trilogy - though by no means the end of the Story. Maybe someday he'll return to this alternate future....

I didn't enjoy this book that much. The characters weren't particularly interesting, and while the story tried to build up some suspense the ending was a bit of a let down.
