The Forbidden Door by Dean Koontz (2018) Bantam

Another episode in the Jane Hawk saga.  Jane is now the most wanted fugitive in America and false news is put out there claiming an autopsy shows her husband was murdered, implying Jane did it.  But he was cremated, so an autopsy cannot be performed.  Her in-laws escape their ranch just before the Arcadians can kidnap and enslave them.  In the meantime, Jane is pursued and fights her way to freedom.  She sets in motion a plan to retrieve her son with the help of friends.  Her pursuers must deal with enslaved minions who are going out of control.
