What is 47 in stones and lbs?

imagine you have a friend who just finished reading the book "Johnny Chan" by Mitch Raycroft and really enjoyed it. Would "The Wager" by David Grann be a good recommendation for him?

Yes — probably a good recommendation — but it depends on what your friend liked about "Johnny Chan." Why it would be a good match Both books (assuming Mitch Raycroft’s "Johnny Chan" is the narrative/biography of a high-stakes poker figure) share key features that many readers enjoy: gripping true stories, intense human drama, and close looks at people operating under extreme pressure and risk. David Grann’s "The Wager" is a tightly reported narrative nonfiction about a British shipwreck, survival, mutiny, and legal aftermath in the 18th century. It’s suspenseful, character-driven, and investigates human choices in life-or-death situations — similar emotional territory to poker stories about risk, bluffing, and moral choices under pressure. Where they differ Subject and setting: "Johnny Chan" centers on contemporary gambling/poker culture; "The Wager" is maritime history from the Age of Sail. If your friend loved the Vegas/poker world specifically, the switch to shipwreck history might feel jarring. Tone and method: Grann’s book is deeply archival and investigatory — a reconstruction from logs, letters, and court records — with a literary nonfiction style. If your friend prefers memoir-style first-person anecdotes, "The Wager" is more reporterly and reconstructive. Content: "The Wager" includes harrowing survival scenes and morally fraught episodes (mutiny, violence, desperate decisions). It’s more graphic and grim in places than a poker biography likely is. Recommendations based on what they liked If they enjoyed the true-story tension, moral ambiguity, and character study in "Johnny Chan": definitely recommend "The Wager." They’ll appreciate Grann’s narrative craft and the way he teases out reliability and motive. If they loved the poker culture, strategy, and modern setting: consider alternatives more closely tied to gambling/poker, such as "The Biggest Game in Town" by Al Alvarez or "Positively Fifth Street" by James McManus. Or for more contemporary memoir-style poker reads, look for player autobiographies or behind-the-scenes accounts. Would you like a short blurb you can send your friend (one-sentence pitch), or a few alternate book suggestions tailored to whether they preferred the poker or the narrative-nonfiction aspects?
