Where to Start: Wonder Woman
Wonder woman earth one is a great read! The new 52, wonder woman blood is also a good one.
Wonder Woman: Gods and Mortals is another good start, as it details Diana’s post-Crisis origin and gives us a great look at the gods of Olympus that play such a big role in her mythology. George Perez does an amazing job w/ the updated origin at the start of his run, and it was also the main inspiration for the 2009 Wonder Woman animated movie, which I’d also highly recommend
