Rate this book
When the Aunga’ri come to Earth, they have a thing or two to learn about humans. And they start with our favorite Human Sexuality.This alien race has long since turned reproduction over to the scientists, quelling their primitive instincts in favor of a more peaceful, intellectual society. But when they come to Earth to try and stop a dangerous alien race from destroying the planet, suddenly their primitive instincts are back… in full force. Now they’ll need to learn to manage their desires before they become to distracted to do what they came here for. And they’re probably going to need a few humans to help them with that.

This book contains the complete Human Sexuality series — Parts 1-4 — so you can read all the way through without any pesky cliffhangers! This book originally appeared in Kindle Vella as “Human Sexuality”

This book contains four... volumes? Seasons? Episodes? somethings? (checks book blurb, OK they're 'parts', apparently) ... of what - if the first part is anything to go by - is pure, unadulterated, why-choose alien pr0n.

I like the concept of this, but the execution meant my tolerance for repeated 'insert tab A in slot B' sexytiems scenes, very loosely duct-taped together with some background plot, ran out around about the end of Part 1. So while I'm kind of academically curious about where the book goes from here, I didn't really care enough about any of the throuple characters in Part 1 to keep reading, and the fact that we apparently shift to a completely new set of characters in Part 2 was enough to make the decision to DNF for me.

It's always a good time when humans mix with aliens!

One story flowed into the other almost seamlessly so it was very hard for me to put this book down. This series is funny, and swords DO cross, a lot. There's also a plot. One alien race as destroyer, one as savior come to Earth and the humans don't know which is which. Two triads and a quad make it their business to handle both the daytime business and the nighttime pleasure. This is gonna be a go-to favorite.

The hottest, sweetest ever

Alien romance addicts and ménage fans both will get everything they enjoy from this full-series set of novels. No dark, painful, or dub-con - just deliciously wild and tender love with a bonus alien mind-meld to push the pleasure higher. So, it turns out human-alien relations benefit Earth and aliens too.

Lots of plot and lots of heat.

Ms. Pike has given us a spicy tale with lots of great characters and an entertaining storyline that kept me reading for hours. All three thruples from the individual stories are combined here into a smooth blending that centers around the theme of undeniable love between the partners; some human, some alien, but all connected emotionally.

The spice was nice

The spice was the only reason I finished this. This was probably the worst edited book I've read. I'm not sure it was edited at all. One of the stories had 2 chapter 7's. The errors were on every page and it was incredibly distracting.

3.5 stars. Would have loved an epilogue for all the couples.

DNF at page 129
I liked the beginning, but I didn't like the end of part 1. Not interested in where this is headed.
