Every Now and Then by Karen Kingsbury

A wall went up around Alex Brady’s heart when his father, a New York firefighter, died in the Twin Towers. Turning his back on the only woman he ever loved, Alex shut out all the people who cared about him to concentrate on fighting crime. He and his trusty K9 partner, Bo, are determined to eliminate evil in the world and prevent tragedies like 9-11. Then the worst fire season in California’s history erupts, and Alex faces the ultimate challenge to protect the community he serves. An environmental terrorist group is targeting the plush Oak Canyon Estates. At the risk of losing his job, and his soul, Alex is determined to infiltrate the group and put an end to their corruption. Only the friendship of Clay and Jamie Michaels—and the love of a dedicated young woman—can help Alex drop the walls around his heart and move forward into the future God has for him.
