The Guardians of the Time Stream is a steampunk-ish series set during the reconstruction of the United States in the decades following the Civil War.
Technology is on the rise, with locomotives and steam-powered industry, airships and other experiments in slightly anachronistic technology. A fascination with travel around the world and the exploration of other cultures, especially ancient cultures, is on the rise.
One thing to keep in mind is that this is an alternative-history Earth ...
The Guardians of the Time Stream, who call themselves the Originators, are determined to ensure the effects of certain events in history don't do any more harm to the planet than has already been done. Their secret: they are the descendants of travelers from our far distant future, who traveled into the distant past to prevent another group of time travelers from altering the world to suit their vision. And as Ess Fremont grows up and learns her heritage, her family's history and their secrets, she takes her place in the battle to protect the world.
ODESSA FREMONT
Ess Fremont already hated her boarding school before discovering the headmistress was trying to steal her inheritance. With her archeologist grandparents presumed dead in South America's turmoil, and her older brother missing, she struck out for freedom.
Guided by her grandparents' maxim to always help where she was able, and aided by their inventions, Ess made her mark. First step: reveal a Resurrectionist plot to the Secret Service before the Southerners could re-start the Civil War.
Disguised as a boy, Ess headed West. Sharp eyes, scientific principles, and engineering knowledge put her in the right place at the right time to do the right thing. Powerful allies included President Lincoln, the Secret Service, circus performers, train inspectors, and Pinkerton agents. Not bad for a girl between her fourteenth and seventeenth birthdays.
If she could only find her missing brother and uncover the secrets their grandparents kept from them...
