I can safely say that with Wonder Woman #14, Diana is back on track. This issue has been a long time coming. I laughed (for good reasons, not out of exasperation) and smiled throughout reading the book.
Diana's attitude is awesome, she knows who she is, she's not whining or sulking, and she even manages to get in a little dig on Batman. The return of Etta was very welcome! Hippolyta's not coming across as crazy. Diana shacks up with monkeys who fling stuff. The plane tech that sugar daddy Batman bestowed upon Diana in Heinberg's run is now based on Diana's Lansinarian plane and was a gift to DoMA, NOT Diana herself. I guess this tech is available to Diana Prince while Diana's real plane is still available to Wonder Woman? At least I hope that's how it goes because I HATED that WW was using Batman's plane instead of her own.
#14's excellent. Gail has created so much excitement in one issue. I can't wait for the future of this title under her tenure!
