The fresco

Benita Alvarez-Shipton, a bookstore manager with a quiet life, finds her world upended when aliens approach her with a plea to deliver a message of peace to Washington, D.C. As unexplained oddities and disappearances plague the United States, Benita is thrust into a mission far more dangerous than she could have imagined. She must confront a dire warning about a predatory extraterrestrial race already targeting Earth, forcing her to leave behind her unhappy home and marriage for a cosmic adventure.
