We are composed of atoms therefore subject to quantum indeterminacy, where does this leave 'free will'

We are composed of atoms therefore  subject to quantum indeterminacy and we do not have a special power to transcend the laws of nature. 

Quantum indeterminacy features are randomness and unpredictability,

 but not free-floating minds that cause atoms to swerve, or neurons to fire, or people to act. So you could read instances of the term “determinism” in my article as meaning roughly “the belief that human action is the product of physical laws” and all the points would remain the same.
The kind of free will  that probably exists is one that is actually entirely compatible with the laws of nature, those pesky atoms,  as we know them.

 So 'free will' doesn’t happen at the level of quantum events, or even of individual neurones. It happens at the level studied by 'folk' psychology—the level of decisions, deliberations and imagination.
