In 'Under the Dogwood Tree,' Ronnie Callahan's hard-fought rise to becoming police chief of her town hangs by a thread as she navigates complex relationships, loss, and the heavy burden of a past tragedy. Her professional world collides with the personal when she's forced to work closely with her charming ex-husband, Officer Tony Lombardo. But as they rekindle a tentative friendship, healing from a decade of pain and regret, Ronnie's life is once again turned upside down by the arrival of Dr. Aidan Foster, a sophisticated new man who could offer her a different future. Complicating matters is a stalker lurking in the shadows, whose obsession and plot for revenge threaten to destroy everything Ronnie and Tony have worked to rebuild.
