Perhaps you are referring to this book:

Across Atlantic Ice

Essentially says that the Solutrean people of western Europe settled the Mid-Atlantic seaboard and inland, and led to the pre-Clovis and Clovis cultures of North America. And disproves the initial peopling of America by eastern Siberian people after the Ice Age.

Excellent book.

I’ve never heard of that book, but I love history. I’ll have to see about reading that one.
