FBI Special Agent Katie Winter is no stranger to frigid winters, isolation, and dangerous cases. With her sterling record of hunting down serial killers, she is a fast-rising star in the BAU, and when a woman is discovered in the middle of a frozen lake, Katie is the natural choice to partner with Canadian law enforcement to track the killer across the brutal and unforgiving landscape.

Yet Katie’s past haunts her, demanding her attention and dragging her down into a well of secrets.

In BELIEVE ME (Book #4), a dangerous killer makes his way north from Denver, heading for the upper reaches of Canada and leaving a trail of victims in his wake, all caught in his signature macabre traps. The FBI needs Special Agent Katie Winter to team up with her elite cross-border team to hunt him down—but in the remote northern regions of Canada, will this diabolical hunter lead her straight into a trap?

In HELP ME (Book #5), a new serial killer strikes outside of Seattle, and FBI Special Agent Katie Winter is summoned when he crosses the border to strike in Vancouver, too. With victims tied to logs and sent downriver, it appears this is the work of a deranged logger—and yet, after a shocking twist, Katie, facing her own demons, realizes that nothing is what it seems. Will Katie enter the killer’s mind in time to save the next victim?
