Crossover time! The Krakoa-era X-Men, Kieron Gillen-penned Eternals, and dead Celestial residing Avengers cross paths in a heck of a book. What seemed like a setup for at first a simple brawl, and then a straightforward superhero triumph, twists and morphs into a metaphor for collective moral responsibility and climate change? Whatever this book is, Gillen writes the absolute bajeezus out of it, and we gush appropriately.
