This week, the SciFri Book Club kicks off our first book for 2015: David Grann’s non-fiction tale of Amazonian exploration, The Lost City of Z. For Book Club newbies, the concept is simple: Read the book, then discuss it with authors, scientists, and fellow SciFri listeners on-air and online using the hashtag #SciFriBookClub. This session, two guest readers will join us: archaeologist Sarah Parcak and writer Jeff VanderMeer. So get reading, and don’t forget to call in during our wrap-up discussion of the book with Jeff and Sarah on February 6th. Keep an eye on this page for updates, and hear a clip from a SciFri interview with David Grann below.

Those who will receive a free book will be notified within a week. If you weren’t among the first 20 to sign up, you can get a 30 percent discount if you order The Lost City of Z from Powell’s Books using this link.
