Longbourn Math by Wade H Mann

What if Elizabeth Bennet did the math?
When Mr. Collins arrives at Longbourn with his proposal, a financially clear-eyed Elizabeth does the unexpected: she examines it seriously. Weighing the advantages and disadvantages with the precision of a natural philosopher and the wit of the woman we know, she sets in motion a chain of events that will alter the course of every Bennet life—in ways none of them could have predicted.
This is Pride and Prejudice as it might have been had Elizabeth’s intelligence been paired with a gift for mathematics, science, and philosophy.
Set at the height of the Age of Enlightenment and the dawn of the Industrial Revolution—when Newton’s calculus was a century old, James Watt was still alive, and the chemical revolution was reshaping human understanding—Elizabeth navigates Austen’s world armed with tools her creator might have envied.
The story follows this most unusual young lady through a series of extraordinary challenges to multiple hard-won happy endings. The mathematics and science are authentic to 1812, but nothing beyond basic arithmetic is required to enjoy the journey.
A novel for everyone who always suspected Elizabeth Bennet was capable of far more than her world allowed her to show.
