The interest in the STE series continues to grow, as the story continues to expand. In this, the latest part, you will learn more about the future of 115 and the other captives, as the Doctor and Trainer continue to bend these prisoners to their will. With the fear of exposure, the Doctor has to make some radical decisions. The problem with haste is that it can create opportunities for escape. Something the Doctor can't allow to happen. This part also includes a surprise that will change the direction of the story significantly.
My review for the serie (1-2-3-4) Too much sex scenes, fantasy, for not enough story. That's often the big deal in those erotic bdsm novels. What's a pity, the books could have been a great interest, but unfornunately the author let us down, without even a real ending. For exemple I would have liked an ending with a love affaire (between boss/slave) or an escape, or a police good catch, or a big rebellion from the slaves, perhaps some dead among the bosses... I don't know but something exciting! Here just nothing like that, we even end not knowing what happen to our lovely beautiful slaves... Disappointed.
Though there is no book 3 to get number 4 is promising. Though very short even for the money. Well worth it. Book 4 continues as a fill in and as a good book should, it leaves you wanting to know what else is going to happen. Hope book 5 is out soon.
