About the book: year / First there were the powerful ancients. They changed their world and people as they pleased. Then the world ended. Then a new one arose from the ruins of the old world. There were fragments of the power of the ancients left in it: non-humans, nicknamed reptiles. They were feared, hated, destroyed. And all these joys fell on a simple student - a great guy - when a train crash took his life on his home world. In a stranger, he woke up no longer human. I had to worry about education again: learn to live in the skin of a reptile. And teach this to the companions from the ill-fated train - defenseless, deadly vipers.
