The Ledger of Lost Artifacts and Civilizations
Not every mystery needs a lost continent. This book investigates fifty-nine real and often overlooked puzzles from the ancient and modern world: a temple older than farming itself, astonishing structures, out-of-place artifacts, and technologies lost to time. Each case is weighed honestly, with a clear ledger of the case for and against, so you can make up your own mind. Some cases collapse under scrutiny. Others remain genuinely unexplained. All of them are stranger than Atlantis.
