Katie LeClair has finally settled down as the new doctor in Baxter, MI. After years of moving, schooling, and training, she wants nothing more than to find a place she can call home, and a small town outside of Ann Arbor seemed perfect.

Katie quickly gets to work in building a life for herself in Baxter, and beyond reviving her love life, she also finds a pair of business partners in a team of father and son family practitioners. But that idyllic dream is immediately shattered when one of her patients is found dead. That wouldn’t be the worst thing, except the death is ruled a suicide, and as evidence has it, the suicide was a result of the medication Katie had prescribed. But she doesn’t remember writing it.

When a closer investigation reveals it was murder, Katie is catapulted into an off-the-books investigation that leads her down a dark path of past secrets. But someone is willing to kill to keep part of the town’s history in the shadows, and Katie must race to find out who before it’s too late.

The idyllic town of Baxter, Michigan, seemed like the perfect place for Dr. Katie LeClair to settle down after years toiling in medical school—until the murder of a patient shattered the peace she had found. Now on the mend and balancing the responsibilities of a new house and the joys of a new romance, Katie is finally ready to start enjoying life. But danger arrives just as the town is gearing up for its annual Halloween festival—and once again, this doctor-turned-sleuth will have to unmask a killer in their midst.

Trouble comes in threes this Halloween. Katie sees a new patient who has just been released from prison for a murder he says he didn’t commit. Inexplicably, the patient suddenly goes missing. And matters take an even more sinister turn when a college student who had been investigating Katie’s old murder case is found dead in the woods near Baxter.

Could Katie’s involvement with the case be responsible for the student’s violent death? Is her new patient truly a cold-blooded murderer? Is this Halloween about to become a real-life horror show? Katie embarks on a desperate race to find the truth in Do No Harm, the second gripping Dr. Katie LeClair mystery.
