Need to finish reading "The Lost Symbol"

My hubby bought Dan Brown's new book (The Lost Symbol) 3 weeks ago. The story is interesting and I always imagine myself in the character of Chief Sato. I wanna finish this book as soon as I can. After visiting Rome last month, and checking out the 'must-see' places there, my next wish is to visit Washington D.C. Oh but I just remembered what my hubby told me after our trip to Rome...he wants to visit Greece next. Then we gotta save now for our next trip.
