"The Lady of the Lake" by Andrzej Sapkowski

Nimue, as the Lady of The Lake says her real name is, appears as a major character in the first Witcher game by CD Projekt Red and you can even bed her if you do the right sequence of actions and dialogue options.  Not, so in the book.  The Lady of the Lake together with a oneiromancer lady, a few centuries in the future, are trying to figure out the exact events that happened around the lodge of sorceresses, Ciri and the wars, as in their time they only exist as archaeological evidence and  in well-censored books.  They are able to discern most of the events as they really happpened, not as the censored books describe them, and pinpoint the exact time that Ciri will pass through their time and space, as Ciri can travel through both.  They both witness Ciri appearing in the sky above their lake for the moment, and then disappearing again in another timespace jump.  Nimue has regular sex with the King Fisher in the book, while in the game that is only vaguely hinted at.  Maybe so Geralt doesn't get offended?  As every man likes to think that the women he's ploughing waited their entire lives just for him, and no other did even come close to qualifying.

In another world Ciri meets Galahad who wants to take her to Camelot to meet King Arthur.  Borrowing much?  Seems like a ploy to increase word count.  Hey Sapkowski, isn't it enough that you lifted a gazzilion things straight out of Tolkien and Moorcock?  And you had the guts to ask CD Project Red for more money, after you declined any profit and merchandise sharing outright and asked to be paid fully in advance?  You didn't think Polish devs could whip out an amazing game?  Better than the books, that's for sure!  And that crappy Polish movie and series (let's hope Netflix doesn't completely screw it up, like with Altered Carbon).

Anyway, I digress.  Everything here is just my personal, non-binding, time-specific opinion, in any case.  So we go back to where we left things in the other book.  Leo Bonhart is now at Vilgefortz' castle, and it seem the two of them are sharing the role of the 'main villain' in this series.  But fear not, our heroes get to the castle eventually, but not before Ciri, who somehow just walks in (???) and surrenders her weapons, so that Vilgefortz can expressly tie her to the "raping chair" and proceed to tell her how he will impregnate her with his own sperm, but through a glass apparatus, as she's not worthy to receive his penis inside, and then cut out her placenta while she is still alive and pregnant.   Bonhart wants to rape her here (he had many chances before), but Vilgefortz shushes him away.

Not to worry, Geralt and company are here, after spending a great time in Touissant (go play Witcher 3, Blood and Wine DLC for a feel), the land of wine, sex and some honey.  Of course, our little fellowship from last time goes head-first into Vilgefortz castle and most of them manage to get themselves killed in the process.  Ciri kills Leo, but it is a bit of anti-climatic, since it doesn't last long, and Ciri is definitely not vengeful (or deranged) enough to make this passage more entertaining.  After all, that animal Leo Bonhart was one of the most vicious, cruel and deranged murderers in the entire series of books, which do not lack deranged murderers, quite on the contrary.  Well, Ciri just slashes his throat and walks away not even watching him die choking on his own blood. 

Neveryoumind.  Geralt eventually reaches Vilgefortz, which is very unimpressive as villains go, and after some mediocre fight, with Yennefer, cuts him in half.  Regis dies unfortunately.  So also do Milva, Cahir and Anguilleme.  Sad.

The book continues for another 50 pages after the defeat of Vilgefortz and it is mostly about political intrigue, the lodge of sorcerresses, politics, Ciri and Geralt trip of revenge and reward, etc.  Geralt and Yennefer get killed at some peasant uprising (after surviving pretty much the entire world of monster and enemies in the last 7 books).  Ciri maybe revives them.  Maybe not.  At the end Ciri leaves with Lancelot for Camelot.  Or does she???
