+# Books I
+
+## Specification
+
+Build a search form that lets the user enter a book title. The Sinatra app will use HTTParty to fetch the data for the chosen book from Google Books and display it on the page. Display the cover, as a bare minimum.
+
+## Sample URL
+
+https://www.googleapis.com/books/v1/volumes?q=title:Ulysses
+
