Aetherborn 3: A Paranormal Urban Fantasy Romance with Found Family, Magical Bonds, and High-Stakes Heat

by Jason Marino

I never meant to bond with one woman, let alone three.
Kara holds us together. She’s fearless, loyal, and impossible to ignore. Iyoni carries the weight of protection with quiet focus and lethal clarity. Tereza brings passion and power, every bit the SPAR agent when things turn ugly.
And when people are dying in my name, they're the reason I keep going.
They’re bound to me, and that makes them targets too. Reznik is coming for us with mind-controlled killers who could be anyone, anywhere. Washington can’t decide if we’re easier dead or dangerous.
We anchor ourselves in each other, in love, in rage, and in refusal. We forge oaths that bind us tighter and perform warlock rituals so intense my bonded have to drag me to bed after. Not like that. Well… not only like that.
But it’s not enough. We’re losing this fight to an enemy with no face, who deals in lies and turns innocents into weapons.
This isn’t a love story. It’s a war.

About the author

I've been writing since I was sixteen - many years ago now - and my passion has always been fantasy and romance. Fantasy offers the escapism that I love in stories, and what would life be without the chemistry of romance? Wholesome, dark, angsty, unrequited, devoted, adoring, angry ... I've written them all. Lived most of them, too.

A great stopping point

Jason said this might be the last one for now and I'm ok with that, I would like a second arc because we have many unanswered questions and doors that were left open so hopefully he just takes a break and comes back to this one. The story and characters are all all still fantastic but SPOILERS.

I really wish he finished Emma's come back arc with a bond. I know it's basically confirmed that it will happen but if this is the last book it's gonna suck not having that pay off.

I found it a little contrite how the main antagonists keeps getting away...some of the decisions fail in what seem like extremely obvious ways, like sending a bunch normal people to ambush a mind controller while the mc stands around outside doing nothing, goes exactly the way any logical person would assume, they all die and he runs away again...Not really a fan of mind control in any context, I think I found three instances of it that I actually liked reading. The chemistry was still good, and the plot and writing are still good. I'm excited to see what the author does next. Glad this author seems to be sticking around, we need more authors that don't just want to write erotica.

I really enjoyed this trilogy, and this final book was no exception. The plot moved well, despite the same primary antagonist being used for a second book. And I liked that the author showed the internal debate on adding more bonded, as well as his decision to not do so during this book.

The author mentions this was a planned trilogy, but they are debating continuing the series. I think it could be done successfully, since the author queued up two likely bonded women in this book. I'm not sure how they will pull it off, since the MC is already OP as all get-out, and two additional women would make him even more so. But I'd give it a whirl if they do.

Ez most kicsit hosszúra sikeredett, egy egész picit mintha leülne helyenként a tempó. De hozta, amit az előző kötetek, szóval nem rossz ez sem, a mínusz csillagot amiatt a csalódás miatt érdemelte ki, hogy a hárem nem bővült tovább. Pedig két (és fél) remek jelölt is akadt.
Ami enyhíti a csalódást, hogy az utószóban belengette a szerző, nem kizárt, lesz még folytatása a történetnek. Vagyis bővülhet a hárem. Sajnos egyelőre nincs céldátum, valami másról szeretne írni Jason, amit megértek, én is belefáradtam kicsit a végére, pedig én csak olvastam. De némi pihenő után biztosan kíváncsi leszek a 4. könyvre is.

There definitely needs to be another 3 books

This was a great trilogy. There needs to be another one. Without getting into spoilers, it's already set up for it pretty much perfectly with the three new girls to become bonded. Come on JM, three more. We're waiting.
