If You Could Recommend Three-Body in One Sentence, What Would It Be?

Every time I recommend Three-Body to friends, it is an interesting challenge. The trilogy totals nearly a million words with extremely high information density, and many people shy away at the mention of 'hard sci-fi'. I have tried different pitch lines: 1. 'There is a sci-fi novel about an alien civilization that decides to take over Earth because their own planet is dying, and humanity engages in a 400-year-long game against them.' — Sounds ordinary? 2. 'Have you seen Interstellar? This is a hundred times more mind-blowing. It has technology that unfolds protons into high-dimensional computers, mysterious aliens who only send but never receive warnings, and a suicidal early warning system called the Cradle...' — Too much info, newbies get overwhelmed. 3. My best pitch: 'This is a novel that tells you why staying silent is the only way to survive in the universe.' — Maximum white space, biggest cliffhanger. What are your best recommendation methods?
