You must read this book if you own your home before beginning HVAC work. Sadly I made the mistake of doing my HVAC work BEFORE I read this book but luckily I was not too far off the mark. Most HVAC professionals sadly do not actually know the "whys" of what they are doing and simply offer cookie cutter solutions that do not fit what your house needs – especially an existing home.

Things to remember - If you want to do anything, ensure you also insulate your home! Ensure there are no leaks in or out of the home. Otherwise, all of the other work will have to use more energy due to leaks of air. - A ductless mini split is highly recommended to condition air around your homes - A ventilated dehumidifier is highly recommended to bring in fresh air & dehumidify it - Ensure you always run the ventilator in the bathroom / kitchen when you are using them - Water moisture is the #1 villain and try to not have temperature differences in surfaces that will cause moisture to develop - A manifold is a way to send hot water through a smaller plastic pipe such that less water looses heat as it stays in the piping - Try to prevent thermal bridges to ensure home is fully insulated

This is book #4 in the series, but it's not the fourth part. Apparently there's a short story, "Omega Night", and it contained both plot and character developments that significantly impact this book. However, even on the official author's website it's not listed between books 3 and 4. It's listed after the final book, among other "related works".

And the author doesn't really do a good job of recapping what happened, it's just an abrupt jump, and now Hope/Astra's angsting over a new crush that started during that book, freaking out over a danger to one of her friends that's due to events in that book, and a number of other sudden changes.

And these changes continue to casually come up over the course of the entire book, so that put a serious damper on my enjoyment of it.

Beyond that, the premise/setting was unique and somewhat interesting, but a lot of it felt like repeating "same song, different verse." Just marking things off a checklist. Astra has a crush that she doesn't want to act on (thankfully not the same one as at the end of book #3). Astra asks for advice, then ignores it in a way that could cause trouble for the one who gave it. Astra manages to get separated from her team (but thankfully not abducted this time). Astra makes mistakes and spends time berating herself. Important rules get massively broken but a loophole means it's okay. And the Perfect Defenses get destroyed via the most plausible method, which somehow no-one saw coming.

I did really like that, after introducing a terrifying Islamic terrorist supervillain in book #1, the author chose to introduce a character that showcases the more peaceful side of Islam. I wish the character was ongoing, but it doesn't look like he will be.

I really didn't like the friend drama for this book - it felt pretty contrived, but Astra was utterly poleaxed. Honestly, the number of times something relatively trivial knocks Astra so off her stride that she can't think straight for several days should probably be cause for serious concern among the team leadership.

After a break of reading PFH, I've started reading some of his books again. I still absolutely love Pandora's Star and Judas Unchained. I really liked his previous long space opera (Night's Dawn) but this universe feels a bit more fleshed out. Cars and trains (oh, the trains) have models and people clearly have preferences. There's discussions about sports and brands and TV and paying attention to some of it now rewards later on, but not in a major way.

The action is good, the science is fun, but unlike his next trilogy in this universe, it doesn't feel cartoonish. The Void Trilogy to me feels like a lot of technobabble and deus ex machina. Book 1 here starts well.

But it's difficult to ignore the sex. Everyone is constantly horny and having sex with at least one other person. In fact it is stated in the book that after a human goes through medical rejuvenation, there are whole planets for no-strings sex. Unlike previous books, PFH has calmed down a bit and we don't get a shopping list of positions every single time.
