summer reading

i realized, to my dismay, that my list of things to do over the summer doesn't include any books! i have found a few while browsing amazon, but i need more! so, wise friend list, what books should i try to read over the summer? suggestions of all genres are welcome!

books i think i might want to read:
on food and cooking (harold mcgee)
the legend of sigurd and gudrun (tolkien)
godel, escher, bach (douglas hofstadter)
how doctors think (jerome groopman)
on the line (eric ripert)
blue shoes and happiness (alexander mccall smith)
stumbling on happiness (daniel gilbert)

as you can see, it's a short and eclectic list and could use many more suggestions!
