Stas survived and returned home, managing to visit not only the Root and Conjugate Worlds, but also meeting the inhabitants of the Secret City, about whom only legends remain on earth, but who for thousands of years have been guarding the conjugation zone leading not just to the Root World, but a world that is a Nodal point connecting several root branches. Only, by chance, he thwarted many other people’s plans and launched a chain of events that attracted the attention of ancient creatures to him. As a result, they are now looking for him, and Stas is forced to start hiding, lost in the vastness of the root worlds. But the chain of events launched by Stas will affect not only his life, but also ordinary inhabitants of the Earth, although he himself does not know about it yet. From the author: The second book in the System Engineer series. After writing the first one, I thought that I might rename the series to “Conjugation.” The title of the book is “The Changeling”, which is also not final. The book at the publishing house will be divided into two. Therefore, here too I renamed the title to 2. The Changeling. 3. Owner. The next book in the series will be released at number 4.
