Buckle up for a double dose of suspense and action in this two-book thriller set from USA Today bestselling author Melissa F. Miller!

CRITICAL VULNERABILITY (Book 1):

Government records, medical equipment, elevators, security alarms ... they're all remotely controlled and monitored by computerized industrial control systems. It's convenient, efficient, and potentially deadly.

Assistant U.S. Attorney Aroostine Higgins has put her personal life on hold to join the Department of Justice's elite Criminal Division. She's about to prosecute a major bribery trial—one that could make or break her career.

But everything's going wrong.

Her pretrial motion vanishes from the federal court's electronic docketing system. Her apartment catches fire. Routine dental surgery turns into a near-death experience. By the time Aroostine realizes her string of bad luck is anything but random, the stakes are greater than the outcome of a high-profile court case.

Determined to win at any cost, a hidden enemy threatens to destroy her—and the only man she's ever loved—unless she can stop him. Now, it's personal.

CHILLING EFFECT (Book 2):

Rumors of money skimming, murder, and stolen military weapons swirl around a Central Oregon reservation.

Aroostine is sent to investigate in the hopes that her Native American roots will help her win trust in a community wary of outsiders.

She arrives to find her would-be informant executed in his home. As she digs deeper into rumors and the murder, she butts heads with tribal authorities bent on solving the crime and doling out punishment on their own terms.

After she and her husband Joe narrowly escape a deadly ambush on the reservation, she has no idea whom to trust ... and who wants to kill her.
