This is book three of the Prisoners of Blackstone series and sees Nas (Masima), a witch but also a seer, and her three mates, human bounty hunter Bane, alpha wolf shifter Ambrose and alpha vampire Christian stuck in the worst part of Nightstone Prison for Supernaturals. Their food is tainted to ensure their natural powers are reduced and their magic is being drawn out from them, to feed the elite’s desire for a drug that can give them temporary supernatural powers, called Karma. On their side of the prison, under Christian and Ambrose's control, the vampire and shifter factions have agreed to a sort of peace with the witches. The warden was about to kill them all, but Bane and Nas managed to stop him. Nas had another vision just as Christian, Ambrose and some of their people came out armed to the teeth with whatever they could find, so she sent some to lock up the warden and guard up in some cells. She had to go with Bane according to her vision, before the kill switch could be triggered by the warden somehow, killing all the inmates and any of the Black Guard who hadn’t left yet. Nas tells Ambrose and Christian to get everyone to the open yard, where they will be safe from the kill switch, but not from any attacks from the air. The warden had been eager to keep the secret of the prison’s production of Karma and it’s other secret experiments, and willing to kill all of them to ensure they didn’t tell anyone about what was happening in Nightstone. Most of the supes (supernaturals) in the prison had been forced into the prison on trumped up charges and even without, never to gain their freedom ever again.
Now Nas and her three mates must try to rescue as many of the prisoners as possible on their side, having no way to communicate with the more relaxed side of the prison, whilst also finding a way to turn off the kill switch and avoid any dangerous parts of the prison. Bane used to be one of the Black Guard, before becoming a bounty hunter and Nas was his hardest opponent to catch. When he got her placed in the prison, he also ended up there and they made peace at long last, as he became one of her mates. Now he has to use what knowledge he has of the prison, the guards and the systems, to find a way to keep them safe and discover what secrets are held within. An old computer terminal in the poisoned zone allows them to discover some of the secrets about what was going on, but also about supes everywhere. It is not just the prisoners that were experimented upon, it was the guards as well. The majority died under the experience, but those in charge kept on going. Her visions keep on happening in rapid succession, some of them giving her multiple versions about what might occur next. Most of the visions show danger and more attacks to follow, some with her losing one of more of her mates, which is completely unacceptable. Some of the prisoners are intent in finding a way out of the prison before any helicopters and Black Guards come for them.
There are numerous attacks made on the prisoners, from inside and out, leaving a number of dead and wounded. One injures the only healer they have and so Nas and her mates try to get through the magical doorway, the head witch and healer from the other part of the prison used to come through. What they find on the other side is definitely not a welcome, but instead a clash of two covens of witches, fighting for supremacy. Nas tries to call for peace and any healer they may have, after hearing the woman they came for didn’t make it through the kill switch surge. Bane has been affected by a substance they found near the poison zone and those who tried to escape are dying from the prolonged exposure to the poison. Bane has the idea of speaking to one of his outside contacts if he can, to get some cameras to film what is happening in the prison. Hopefully, if they can show the truth about supes and what has been happening to all those in the prison. If they can reveal the truth, then hopefully they will no longer be in danger and they can all live in peace. They all have a hard battle ahead, but peace is possible if her seer abilities are showing her the correct vision. Lots of massive secrets and new abilities revealed, danger and death all around, but also hope for the future both inside and outside of Nightstone Prison!
