This book offers barely any plot and zero character development, both ignored in the favor of insufferable amount of quite unnecessary fighting scenes. The book would otherwise have around 100 pages of shallow but pleasant plot.
While I am aware of Salvatore's "matriarchal society only in name" writing, this book hammered the hypocrisy of it into the ground and left it there for me to weep over it. Unlike in Legend of Drizzt, women actually do something other than villainy in this book. That, however, is once again overshadowed by the fact that men still apparently do everything in Menzoberranzan and Ched Nasad. From Gromph getting more screentime than Triel, to Pharaun being literally illegally sassy with Quenthel. Pharaun's behavior is supposed to connect the reader with drow race because, as Drizzt, he is a bit unusual and more bold than any other drow "male". His borderline blasphemous demeanor is excused by everyone, including the author himself. The high priestess, in the absence of her own divine powers, constantly thinks to herself how "Pharaun is too valuable to be harmed in any way", which is mostly the author being unable to comprehend how an actual gendered society works. Lisa Smedman did far better job of this in her Lady Penitent trilogy, even in mere 80 pages I read before pausing to read this mess of a six-book-series. Quenthel, the high priestess, continually refrains from any sort of verbal or corporeal punishment that drow "females" are so notorious for. In regards to that, drow men written by men authors never seem to have any psychological damage showing from the fact that the reader is constantly reminded of "female" cruelty toward "males" in that society.
Throughout the book, "males" are constantly spared the torture, and are the supposed default for any large group of soldiers (women are never mentioned as parts of troops, except when they're specifically "high priestesses"). Author always finds some reason to save any male character, but on the other hand, women are often described dying in horrible, bloody (and deserved) pain. For example, Quenthel did not feel any qualm ordering many high priestesses to mutilate themselves as punishment in the previous book, despite knowing she will one day need those divine powers to rule over the city in one way or the other. When it comes to very rude and disrespectful Pharaun however, she insists, in her thoughts, she cannot treat him badly in any way because she needs his arcane powers. He would've been able to cast spells even if she taught him a lesson with her whip once or twice, the way it would apparently make sense in the "cruel matriarchal drow society" Salvatore wants to portray.
While on the subject of tentative main character, wizard Pharaun, he also, for no proper reason, suddenly attracts two women and is described to be ogling them in the middle of the fight. A jealous unnecessary romantic triangle is also hinted at. One of those two women is an overly sexualized demon succubus (I say overly because the demon she works with, an incubus, is at no point described in a sexual or sensual way), who is apparently suddenly head over heels for Pharaun, even if she is centuries old and has certainly seen better catch than some drow... Furthermore, Pharaun is described to be aroused by the sight of humiliated and subdued battle captive to the point I was sure the book must have been written by a hormone-ridden teenager.
In conclusion, I blame the many downsides of this book on both the author, and Salvatore who oversaw the writing of the whole series. Salvatore purposefully insists on this "matriarchal" society having very little to do with women, and it shows in most aspects of his books. Women are a plot device only as villains. But they are villains for as long as that doesn't impede readers' (and authors') boy fantasies. Because obviously we're out of ideas for what men should do, so it's going to be very interesting to put them into what we think is a society oppressive towards men, and then make them the main characters too. This shows the best when one realizes that out of four pillars of power in Menzoberranzan, only one is dominated by women (and so far, I haven't seen the mention of women in other three). Those would be Arach-Tinilith priestesses/nobles/matron mothers, led by women, who are in turn supported by male dominated wizard school Sorcere, and fighting schooland Melee-Magthere, and also employ the help of mercenary group Bregan D'aerthe (so far no mention of women being part of it).
In Insurrection, the author is also completely unable to portray any sort of personality for women except for "anger" and "self-importance". Mind you, men get very little too, because it's far more important to write extensive and detailed fighting scenes. My reference point is the Brimstone Angels series written by Erin M. Evans who did not bother with thorough fighting scenes or using the pretentiously complex language, but rather focused on developing the plot, as much as both women and men characters.
I will admit I read only 3 Legend of Drizzt books and 2 from the War of the Spider Queen series, and I am open to seeing that hopefully all these things I'm currently complaining on will change in the future. (I am not optimistic, however, seeing that the new Drizzt series that came out in 2015-2016 mostly mentions just Drizzt and Gromph in the summaries...)
I'm not a fan of skipping books and reading the summaries on wiki pages, but this book doesn't deserve those couple of hours it would take to read it. I also recommend just skimming the fighting scenes because they honestly do not contribute to anything.
