Desert Willow by Patricia Beal

After a failed engagement, Captain Andrew Lee James has focused on building a career in the Army he loves. That commitment includes helping a feisty, out-of-work ballerina whose devotion to her grandmother’s dying wish immediately grabs his heart. She’s the one, but will he be able to win the heart of a woman who has vowed to never be involved with a soldier?
College graduate Clara Malone swore to never love anyone in the military again but when her dying grandmother asks her to deliver a love letter to the general who broke her heart decades ago, she agrees and finds herself escorted by a handsome Army captain whose kindness challenges her beliefs. Surrounded by desert willows that shower her path with pretty pink flowers and sing with the buzzing of hummingbirds, Clara enjoys the wild beauty of El Paso—and her time with Andrew—more than expected.
Can she deliver her grandmother’s last love letter without losing her heart to a man who represents everything she fears?
