Germ Theory - The Worlds of Ryn Wilkie #2 (#2 in The Worlds of Ryn Wilkie)

World-walking young surgeon Ryn Wilkie is trying to finish her residency here on Earth, while also bringing modern medicine and antibiotics to a parallel but somewhat primitive Earth.

She wants to improve the plight of women on that world - where they‘re treated as if they're property.

It’s a world at about the technological level as our 1900s. But she can find gold there in the same locations that history tells her they found it on Earth. It’s also a place where a roll of aluminum foil is worth a small fortune!

Meanwhile, back on Earth, the men who tried to rape her and her friend Keilly are still trying—but now they want to murder her after they’re finished.

Oh, and she accidentally discovers another parallel Earth. One that doesn't seem to have any humans...

Travel with Ryn to worlds full of terror and promise.
