According to FreshersLive, it's estimated that David Grann's current net worth is $5 million. When he's not writing feature articles, David spends much of his time thoroughly researching his book subjects.

According to CBS, to write The Wager, David spent two years sifting through archival records of an 18th-century British warship called The Wager.

Then, David flew to Chile, chartered a boat, and visited the island where 145 castaways spent months marooned and fighting amongst one another on the brink of starvation. The reason for their wreck? The Wager was chasing a Spanish galleon dubbed "the prize of all the oceans."

Fans will have to read for themselves to learn more. The Wager: A Tale of Shipwreck, Mutiny and Murder is now available wherever books are sold.
