I've been working for a while to develop a Frequently Asked Questions page to answers the most common reader questions about The Immortal Life of Henrietta Lacks. Well, it's now online, and it addresses questions ranging from why HeLa cells are immortal to how the Lacks family is benefiting from the book. It also includes answers to commonly asked publishing questions, like, How do I break into science writing? You can read it online here. If you have burning questions not answered there, leave them in the comments section below -- I'll add to the FAQ as questions arise and time allows.
