The Iron Ring - Matty Dalrymple - Bog

Lizzy Ballard is headed to Arizona on a mission of vengeance: to kill the man who murdered Philip Castillo’s prison mentor.
Meanwhile, Louise Mortensen and Mitchell Pieda find themselves under the protection—and at the mercy—of reclusive billionaire Theo Viklund. And Theo is intent on recruiting Philip to his cause as well.
With the lines of communication cut, Theo sends Philip after Lizzy to keep her from executing her life-or-death assignment. As Lizzy’s allies struggle to understand exactly who the enemy is, Lizzy faces the killer, and even her special ability can't protect her.
