what's the best peruvian cookbook? came back from the Inca Trail and want to make their soups!

These are the three books I use, two of which are South American and 1 in pan Latin America. Each has a good section on soups, but also every other kind of dish. So you might want to take Nancy's suggestion and look at the library before purchasing.
1) The Art of South American Cooking by Felipe Rojas-Lombardi (He was Peruvian)
2) The South American Table by Maria Baez Kijac
3) Gran Cocina Latina by Maricel Presilla.
I hope you find what you are looking for.

Another idea...sample recipes and/or cookbooks before you buy a book. Recipes from Web, books from a local library.

Need it be in English?
Found one with great review but it's bilingual. Text Spanish, recipes English.
Crazy, I know.
