an alternate cover edition can be found here Fallen for love. Risen for revenge. Severn knows love. He knows how it feels to fight for love, and have it torn from his reach. He knows that when the killing fields are strewn with the dead, and love is all gone, only one thing keeps his demon heart beating: Vengeance. His life is now a web of lies. His act, a perfect one. His enemy, the guardian angel Mikhail, sits beside him, turns to him for guidance, and even loves him. The time has come to make all the angels fall, beginning with the most powerful of them all. Severn thought he knew love. But he’s about to discover that love takes no prisoners, and as demons and angels clash over London’s battle-weary streets, love will claim the souls of two destined enemies. Primal Sin is a dark gay fantasy with a strong love-story. The series is brimming with savage desires, relentless lies and the bite of vengeance and is not for anyone easily disturbed by graphic scenes.

The fate of the world hinges on their shattered love. But can it be saved? For as long as angels and demons have warred over London, battle lines have never been crossed and humans never hurt. Now, everything has changed. More powerful than ever, nothing can stop Mikhail's crusade of vengeance against the demon who betrayed him. Trapped as an angel, Severn is running out of time. To regain his true form, he must retrieve his wings, but there's one problem: Mikhail. The guardian has Severn's wings gruesomely displayed in the broken City of Aerie, high above London. Weak and heartsick, Severn's power failing, he has no choice but to lie, cheat, and illusion his way back into Mikhail's cold heart or die trying. Destiny thought them fated mates. Was destiny wrong?

An angel and a demon fell in love, and the world went to war... Branded a traitor by his own kind, Severn knows winning demons back will not be easy, but when High Lord Luxen steals Mikhail from his grasp, he has no choice. He’s going to need all the help he can get to find Mikhail, unseat Luxen as High Lord, and build a force to rival the vicious Guardian Angel Remiel’s. Or every last demon will die when the guardian descends on London. Weakened by his treatment in Haven, Mikhail finds himself at the mercy of the demon High Lord. A sly, powerful concubi demon, Luxen is able to manipulate the minds and hearts of those around him. Including Mikhail’s. Is Mikhail’s love for Severn strong enough to withstand Luxen’s charm? Or will he break, unleashing an ancient god’s terrible vengeance upon them all? As the lies of the ancient past come crumbling down, Severn and Mikhail must harness their differences and unite two warring races. They must fight for truth and for love, together. Or all of London will fall.

How far will he fall for love? Samiel has escaped. It's up to Solo to track him down and return him to the enclosures to await Mikhail and Konstantin's punishment. But Solo's only lead is the one demon no angel can trust—the one demon Solo can't resist—the incubus High Lord Luxen. Luxen has offered to help. On one condition: Solo sets him free. Dare he trust the notorious, manipulative demon lord? Can he trust himself not to succumb to the desires Luxen summons within him? There's only one way to find out. \\\* Solo takes place after the Primal Sin trilogy of books, and must be read after Infernal Sin to avoid series spoilers.
