Liar City by Allie Therin

A murder has Seattle on edge, and it falls to a pacifist empath—and a notorious empath hunter—to find the killer before it’s too late

It’s the middle of the night when part-time police consultant and full-time empath Reece gets an anonymous call warning him that his detective sister needs his help. At an out-of-the-way Seattle marina, he discovers that three people have been butchered—including the author of the country’s strictest anti-empathy bill, which is just days from being passed into law.
Soon, Reece’s caller arrives: a shadowy government agent known as The Dead Man, who is rumored to deal exclusively in cases involving empathy. He immediately takes over the investigation, locking out both local PD and the FBI, but, strangely, keeps Reece by his side.
As the two track an ever-growing trail of violence and destruction across Seattle, Reece must navigate a scared and angry city, an irritating attraction to his mysterious agent companion, and a rising fear that perhaps empaths like him aren’t all flight and no fight after all…
