Meanwhile Syd's middle sister Emily has started a new lifestyle blog, her youngest sister Rory is fostering kittens, and Syd renews her relationship with Kelly Green, an FBI analyst she first met while working for the FBI on the East Coast.

In book 3 in the series, it's Halloween and Sydney joins Ezra and his group as they take on an old murder case where the suspected killer has been caught and convicted although Ezra has reason to believe he may be innocent as he has claimed from the beginning.
