Stakes Keep Rising. In this installment of the Sabel Security Thrillers, we find a rather ingenious terrorist plot, ran by someone inside the US. But who? That is what Pia Sabel and her team must find out. Good action, good mystery. Need a resolution to the mystery behind Pia’s parents’ murder already. That plot is starting to get long in the tooth with no resolution. Though the ending here was a bit of a cliffhanger – only tangentially related to said murders. Still recommended.
