It's no easy task to write a sequel to a masterwork, let alone with a couple decades in between, but "The Gripping Hand" manages to the task. The Empire's blockade is collapsing, whilst the Empire is more powerful and consolidated than ever before thanks to the work of Kevin Renner and Horace Bury working as Imperial Spy with enough license to do the deal as they see it. Lord and Lady Blaine are relegated to Sparta at their institute with a break-through technology in dealing with the Moties. Their children are a center-piece in the action, but ultimately ancillary characters to Bury and Renner. In fact Renner's legend is upped ten fold in this tale. The most interesting new character introduced is Joyce, an investigative journalist who revealed the lax that had become endemic within the blockade. Her role in the tale is to show of a more Republican empire, as her journalism isn't attacked but has to be given due-diligence and she is given liberties to report a tale that would have been in the previous book the highest security for the Empire. Running in tow with this is Horace gives a powerful section on how his people of Levant aren't just tolerated, they're accepted.
"The Gripping Hand" does an excellent job at giving the layman a look into what a space battle may look like, slow, constant, dull until terrifying and happening over a long period of time. This book features a colossal space battle for all the marbles involving a multitude of participants. There are more complex issues that call back to the greatness of the "The Mote in God's Eye", as a relationship with the Moties is reexamined with the benefit of both civilizations now knowing and having some understanding of one another's workings and motives. Complex but believable diplomacy with an alien civilization is one of the best reasons to read this series. I enjoyed the scene structure of the latter-half of the book, the blurred reality of "jump shock" is described so well as to confuse the reader (in a good way) as to what the action is or the situation - all taking place during the most precarious moments of this book's climax. The reader comes to care and empathize with Horace Bury as an Anwar Sadat style character who is willing to change and be flexible, adapting their world view for the current climate. A powerful person able to make decisions free of pathos or obstinate will. I also enjoy the balance of strengths and weaknesses to Human civilization and Motie. Moties are super-efficient, caste-based, bred into colonies sharing a common gene pool and familiarity head "Master", they can out-engineer humans, out-think humans, out-wit humans. However, they are physically weaker, live shorter lives, have a less agile physiology, live in a system strapped for resources, and of course must breed or die. So they are stuck in constant "collapse" epochs. Whereas Humans for all their weaknesses in organization and engineering to the Moties, by benefit of slower and voluntary breeding, the passing on of information, and loyalty beyond kin, have allowed them a slow and steady spiral up -- with some luck to boot in the discovery of Langston fields and Alderson Drives. This was the original genius of the book's premise is how well devised the two forces are, their strengths and weaknesses allowing for complexities which disallow simple or binary solutions. For all these reasons this book, despite flaws "The Gripping Hand" has, is well worth the read.
However, it is not the masterwork that "The Mote in God's Eye" is because the first half of the book is a rather slow build up to the action-filled second half. Whereas the first book kept a steady, pages flow by, pace by sprinkling events between plot points "The Gripping Hand" spends around 100 pages just working out the details of getting approval for the mission. There's a point being made I'm sure, about bureaucracy and what is later called the "ossification" of the blockade and therefore the Empire, but it's out of sync with the first book. The Moties series accomplishes that excellent trick in fiction to have world-building that's seen but not heard. Aspects of a First Empire of Man, who ostensibly still have greater technology than the Second, as they could terraform worlds, isn't explained beyond that and adds to the surge to read forward wanting to unravel the mystery. This went doubly so for the Moties and their civilization. Less questions are being asked in the first half of the book, lots of dinners, reunions, set-up, but thankfully the second half the book makes this section worth the time spent in getting reacquainted with our characters. I also thought "The Gripping Hand" was able to weave back-story or world-building information into the narrative in a way as to not distract. There's a section on the tool the institute has developed for the Moties that reads like an Encyclopedia-Britannica article but because of its place in the story comes across as useful and fine.

What bothered me about this tale, even while the overall movement of the story is great, is that it left subplots unanswered. During the Hook when Renner is on Maxroy's Purchase the saying "in my gripping hand," is explained away as colloquial. I found this unlikely and too convenient. Further the Governor of Maxroy's Purchase is suggested to be corrupt and able to move, in fact in communication and trade with an Outie world, but it's never answered. This one happens so early in the tale, but the nature of it makes things feel less resolved in the end. Later Rod and Sally Blaine are suggested as leaving to New Cal to form the institute headquarters there again. Perhaps it can be left at that, but they are revisited - along with the Motie Mediator from the 1st book Jock - as they're put back in charge of the Imperial Commission on the Motie Civilization. Jock suggests Blaine with be given a fleet, with Jock understanding these developments would hold everything at stake for Motie Civilization. They are never revisited again. This is doubly disappointing, as again it makes the book feel less resolved - especially as no epilogue section follows the main plot - and leaves out two of the most likable characters, along with ultimately the hero of the first tale. I wanted to see Rod Blaine's star rise a little higher, instead what occurs is that he is relegated to a paper-pusher. Lady Blaine is a bitter woman. Their children, while always in the middle of the action, have nothing to do with much that is occurring beyond being bargaining pieces and towards the final peak of the book's plot Chris is milquetoast compared to Freddy and Renner, he's just around. Ruth Blaine, a sensitive half-seer half-Machiavelli, is described in the final analysis as being sort of half-human. This seemed an odd way to treat the epic heroes of the first book, seemingly the analogy for what will be - with this victory - the final stagnation of the Empire. Lastly, there's a Motie Civilization that beams a messages to Sinbad and Atropos which has ostensibly existed through all the "collapses" and has exhaustive information and knowledge. This Motie Clan, named Alexandria, is ordered to be part of all negotiating and included in any treaties that occur. They are never mentioned again. These subplots and changed nature of the Blaine's - from under-dog Aristocrats proving themselves through action to tokens - is why "The Gripping Hand" has the drama and complexity of the first novel but lacks its accomplished ending and polish.
