It's Christmas Eve and Detective Alex Cross has been called out to catch someone who's robbing his church's poor box. That mission behind him, Alex returns home to celebrate with Bree, Nana, and his children. The tree decorating is barely underway before his phone rings again--a horrific hostage situation is quickly spiraling out of control. Away from his own family on the most precious of days, Alex calls upon every ounce of his training, creativity, and daring to save another family. Alex risks everything--and he may not make it back alive on this most sacred of family days. Alex Cross is a hero for our time, and never more so than in this story of family, action, and the deepest moral choices. MERRY CHRISTMAS, ALEX CROSS will be a holiday classic for years to come.
