The Mechanical, by Ian Tregilis, is an adventure story set within an alternate history in which Christiaan Huygens used alchemy to create and enslave thousands of mechanical people, which allowed the Dutch to maintain a worldwide empire for over 250 years. The story puts you inside the perspective of a range of characters, including a mechanical named Jax, a noblewoman at the head of a French spy network, a Dutch pastor, and many more. It is a fun read that can be taken at a galloping pace, but if you slow to a walk, there is a lot to think about regarding free will, sectarian religious disagreements, colonialism and slavery, human reliance on technology, and other substantial philosophical issues.

You can read a sample at https://www.orbitbooks.net/orbit-excerpts/the-mechanical/ and the good news is that once you get sucked in (like I did) there are two more books in the series: The Rising and The Liberation.
