About this listen

PI Bridget “Birdie” Hartley thought the storm had passed.
She found her sister. She survived a shootout.
But peace is proving harder to hold than she ever imagined.


With Ada finally safe, Birdie’s only goal is to keep her that way.
But when a buried cache of secrets surfaces,
hinting at a private island summit, a rising force within a dangerous syndicate, and a captive long presumed lost, rest is no longer an option...

What begins as a desperate call for help quickly turns into a deadly trap.
Outgunned and outnumbered, Birdie is on the run once more.
Deep in the Oregon wilderness, a sudden disappearance shakes her team’s fragile unity.
As loyalties fracture and the enemy closes in, Birdie suspects the real threat may already be inside the circle.

This is Birdie’s last mission. Her last chance to break free from the darkness.
The walls are closing in.

Disastrous love affairs, widespread duplicity, and the promise of a life she may never reach.
The final showdown is here. And Birdie will risk everything to end it, once and for all.
