Euclid's Wall - 2020 Edition

An interesting premise and well-thought-out extrapolation. The author put a lot of effort into creating a plausible world after a disaster which (nearly) ended everything. I liked the main narrative of scientists and non-scientists on a voyage of exploration in search of a possible solution to what could be a world-ending situation. A number of surprises along the way kept things moving along, although at times the info-dumps of sailing terms and activities, while perfectly reasonable for the characters in the book, slowed things down a bit.
