Type Detective Challenge

This typeface is being used in a book I am currently reading. I have tried to find it with the usual name the font sites but none have identified the font.

The lower case "a" is very unique. It is like an italic "a" used in many fonts but this typeface is not italic.

I love the open and airy feeling of this typeface. It appears that the book designer has used a generous amount of letter-spacing and line-spacing. Also, I have not noticed any hyphenation, which is extremely rare in book design. The book designer, I imagine, is a perfectionist.

Any idea what the typeface is?
