My rating: 3 of 5 stars
Originally published as BEYOND THIRTY in All Around Magazine in 1915 the short novel was then un-published until 1955 when Ace released the mass market ERB paperbacks re-titling it as THE LOST CONTINENT. Sort of a post-apocalyptic Lost World story that tells of a period 200 years in the future where Europe has been decimated by war and has returned to tribal barbarism and overrun by jungle animals. The Panamerican narrator/hero is forced to cross the 30th parallel, which is strictly banned and enforced, and he ends up in England dealing with lions, tigers, and wolves, plus uncivilized natives including a beautiful princess, A pretty typical ERB adventure yarn with the flowery prose of the time and cardboard characters. The hero’s marriage to the queen of England was an unexpected and somewhat outlandish touch. An okay Lost World story that doesn't quite measure up to the Caspak and Pellucidar books.
