True Free Will

Any act of true free will would be an act for which there is no antecedent conditions, an act that does not depend on anything that came before it and so cannot be determined a priori. However, such an independence also makes this act a logical necessity and so it holds over all possible worlds and could not be otherwise. So, if this act of true free will could not have been otherwise, can this act still be considered truly free?
