It happened. Just yesterday, impossible. The world has changed. And this time irrevocably. The united power of the Laxens who invaded Earth swallowed Damon and his family. Kat does not give up - she fights, waits and believes: love will become salvation, and not an Achilles heel, which will ultimately destroy them both. Damon is ready to commit betrayal and take a fatal shot - just to save those who are dear to him. The boundaries between good and evil are blurred. Enemies become allies, and sometimes it is impossible to distinguish one from the other. The circle shrinks, you lose even when it seems there is nothing left to lose. This is the price of freedom, life, love. Read the completion of the series of novels “Obsidian”, “Onyx”, “Opal” and “Countdown”!
