Reading Book

I got two books from Packt Publication for review. One is Ajax and PHP & another is Smarty Web Development. I am really confused to decide which to read first. Finally I have started reading Ajax book first. After two days I tried to read Introduction chapter of Smarty book. Ohhh. the wrong I did. Now I am in great confusion. The both books are sooooooooooooo interesting that I can’t decide which one to stop………

 Waiting for a solution. Otherwise I will continue what I am doing which mean going parallel.
