Semper paratus. Always ready. Caddie Lyle strives to live up to the motto of the Coast Guard—and her father's legacy—as she carries out rescue missions. But when she discovers other career opportunities and meets Guardsman Aven Holland, her heart begins to pull her in different directions. Aven is drawn to Caddie, too, but their duties allow little time together. As danger from Alaska's coast and a secret from the past threaten their newfound love, will they be ready to trust God for a possible future together?
