A seek-and-find picture book that portrays everyday altruistic efforts. Shriver's text invites readers to notice more than 50 heroic deeds in 10 illustrations. A hospital scene shows "Ten Hidden Heroes working night and day, nursing others back to health until they are okay," including medical staff members reading an X-ray and taking blood pressure. Other images highlight people reading to children, working at a food bank, building homes for those in need, running in a charity race, and doing other helpful activities.
