Lilith has just found out she was pregnant from the first antichrist they took in hand, giving both her and Samael a huge shock. Samael wants to be more present than he had ever been with nay of their other offspring, but acting even more protective towards her, has the opposite effect on her, as he tries to keep key information form her until he has absolute proof. He has discovered that someone extremely close to them, has been hiding their magical abilities and the details of a deal they made with the devil himself for their soul, from all of those closest to them. They have asked for the help of some of their children, Hilly, Mammon and Bear, as well as Bear’s partner and witch, Flakinda, to work on stopping this prophecy about the end of the world and the coming of the antichrist. But there isn’t just one antichrist! They have tracked at least five and have managed to get at least two of them so far, to come back to Bear’s fortress and be held there. The blood of one of their oldest friends was used by this person knowingly, to bring about the antichrists, in an effort to get what they themselves have wanted for decades, if not longer.

Others close to them are unable to explain what they might have known about the prophecy and the involvement of those close to them, magically unable to speak of such matters. The angels will have nothing to do with this battle, but if the prophecy is fulfilled, Heaven, Hell and even Earth itself will cease to exist anymore. Those behind this action have their own selfish reasons to bring all this pain to others, hoping for some resolution of their own wants and wishes for their own life or death! The true name of one of their group is key to the evil plans of one closest to them, but it is not something they will easily be able to get. It is something not often shared with others, due to the power it gives that person to control them, no matter what. The shock is who is behind the use of those closest to them and who they are linked to. This is partly why the angels will do nothing to aid in the mortal realm, or so they say, but realisation that this plot will affect all of their realms, means action will be undertaken to support Lilith, Samael and the others, just through indirect means. Lots of angst and desperate disbelief about who is behind all of this prophecy being brought into being, with Lilith struggling with the betrayal, on top of trying to protect this new child growing within her, that is of a forbidden kind. So much to do and little time to do it, as more antichrists must be found and detained, whilst attempting to stop the prophecy from being fulfilled, or all their lives will be over. Some unknown allies will give some assistance in secret, with unknown powers given to Lilith, helping out in the end, along with her son Bear’s partner, Flakinda’s magic. A nicely wrapped up ending to the series with so much to be resolved and the fate of all their worlds relying n their combined powers and determination.

I received an ARC copy of this book from BookSprout, and I have freely given my own opinion of the book above.

Endless Sin delivers exactly what it promises: temptation, chaos, and deliciously sinful tension wrapped in a paranormal apocalypse. Lainie Anderson leans fully into the angels-versus-demons energy, raising the stakes both emotionally and cosmically, while keeping the spice level high and the pacing addictive.

The chemistry in this installment is intense—the kind that simmers under every interaction before combusting into moments that are equal parts passionate and dangerous. Desire is tangled with destiny here, and it works beautifully. The romance feels forbidden and charged, perfectly mirroring the end-of-the-world atmosphere closing in around the characters.

What really stood out was how the plot and spice were balanced. The apocalypse isn’t just background noise; it actively shapes the choices, sacrifices, and emotional weight of the story. Angels aren’t purely virtuous, demons aren’t purely wicked, and that moral grey area makes everything far more compelling—and far more sinful.

While a few moments felt slightly predictable for the genre, the payoff was still satisfying, and the emotional tension more than made up for it. Fans of paranormal romance who love high heat, dark themes, and supernatural chaos will absolutely devour this.

Overall, Endless Sin is a seductive, dramatic, and spicy continuation of the series that left me eager for more.

Perfect for readers who love:
🔥 spicy paranormal romance
🪽 angels with secrets
😈 demons with temptation
🌑 end-of-the-world stakes

This was an amazing ending to this series. It really built up along the way, and this was an explosion. Everything coming to a head. And the chemistry between these two was so hot. This has to be one of the best series I’ve read in quite sine time. I was literally on the edge of my seat the entire time. In sad that this is ending, but it was so worth it. The writing was absolutely phenomenal. It was intense, intriguing, and so captivating.

I received a free copy of this book and am voluntarily leaving a review.

Lilith and Samael are back in book three and the final book in The First Curse series. This book picks up where book two, Fated Sin, left off, and the action doesn't stop until the final page of this book. Things take some crazy turns, and the story held my attention from the first page until the last. Great writing, well developed characters, and wonderful world building make this a page turning read. I voluntarily reviewed a copy of this book.

This is book 3 of the series. I enjoyed reading the conclusion to the series. It is quite well written. I recommend for 18+ because of the amount of spice.

A dark paranormal romance with fallen angels and demons trying to stop Armageddon.

The author does an excellent job with the storyline, and it keeps you vested in the story. Her writing is smooth flowing and you don't want to put the book down. It's dark but very well written.

The characters are great and you can't help but cheer them on. The characters are named from the bible but you take from it what you want. I took it as a work of fiction and nothing more.

I love paranormal books and this one didn't disappoint. Three books in the series and well worth the read if you like paranormal books as well.

Highly recommend
