That's a pretty big topic, so it'll be hard to get you good recommendations. Is there a particular region or aspect of Latin American culture you're interested in?

For a basic introductory book about the legacy of Indigenous people in Mesoamerica, I recommend you the book The Legacy of Mesoamerica: History and Culture of a Native American Civilization by Carmack, Gasco, and Gossen. They bring their discussion of mesoamerica into the present and rise the important question as to whether or not we can still talk about a cultural area called mesoamerica in the present day
