The first thing I did when I woke up yesterday to find The Sirens on Mars on the @nytimes 100 Notable Books of 2020 list was go back and reread my acknowledgements. Thank you again, from the bottom of my heart, to everyone who helped me bring this book into the world.

"Consider the difference between a seashore littered with water-worn pebbles—a situation that could easily be ascribed to a lifeless process—and one strewn with intricately sculpted seashells.” Great reporting on agnostic biosignatures by @nataliejelliot.. https://t.co/03Dft6VjiR
