What’s unique about this book are the insights into the relationships between the main characters of the CRISPR saga. The loyal friendship linking Jennifer Doudna and George Church. The growing distrust between Doudna and Zhang. Doudna’s sorrow that she and Charpentier have drifted apart, personally as well as scientifically. The last point is indeed a melancholic note in the Nobel-ending tale. Why did their friendship fall apart?
