Mostly Harmless Adams, Douglas

The fifth instalment in Douglas Adams' gloriously absurd Hitchhiker's series finds Arthur Dent still wandering the galaxy, slightly more world-weary and no closer to a decent cup of tea. Adams takes a darker, more melancholic turn here—think existential dread meets intergalactic bureaucracy—while still delivering those brilliantly sideways observations about life, the universe, and everything. Ford Prefect returns, there's a mysterious package, parallel Earths, and a daughter Arthur never knew he had. It's clever, bittersweet, and quintessentially Adams.

Perfect for Hitchhiker's completists and anyone who likes their science fiction served with a hefty dose of philosophical wit.
