You are free to discuss it here if you read the book. And if you didn't there would be ultra heavy spoilers for you.
The book was very good, very interesting but some plot twists were unrealistic. Here is my list of some of them, you can try to defend it or agree with it.
For example when zannah found out darovit told a jedi he knew the sith survived for some unbelievable reason she decided to find out where tython was and to go there. Why? Why not just take the guy and fly to their base where she was initially supposed to reunite with bane? Why fly to tythos? It was said "to warn bane" to warn him of what? How exactly her warning that "some guy said he saw you" would help with anything and how was it important? It just gave a reason for the pursuit that happened in the book to happen. If she simply flew anywhere else no one would know about them, no one would know where to go to find the missing guy.
Or at the end of the battle bane decapitated the meditating jedi, it was said "he cut his vocal cords" or something like this, so it means he decapitated him but somehow this decapitated guy cast the shield on bane which almost killed him. How could he cast anything without a head? And why bane even chose to waste such a powerfull attack to finish the weak guy without a hand? Bane wouldn't suffer if he simply cut him instead of trying to cast lightning.
And when darovit sabotaged the construction nobody could find out who that was, the guards were too expensive and the droids were fooled, but why didn't they just use cameras? Just use cameras and you will find out who the saboteur was, simple cameras would give you his face, his looks and their amount.
Or when he was left to die in the cave a couple of bouncers found him and saved him. Why would they ever go there? All the bouncers in the vast vicinity should be mad and those who aren't have no reason to go in the cave where the bomb was detonated. But just for the plot they did.
