Available on Comixology and at your local store, DC Comics Presents: Wonder Woman Adventures #1. It reprints four issues from the Adventures in the DC Universe series, focusing on Wonder Woman (as well as one short Batman story by Timm & Dini). From the DC site:
For those unfamiliar with the title Adventures in the DC Universe, it's one of the dark crevices of the DC Animated Universe. It was a tie-in meant to coax lovers of the animated series into the mainstream universe. It was made before the third season of Superman: The Animated Series, and it shows. Aquaman, Kyle Rayner, and the Legion of Super-Heroes were introduced before the animated show did - and it followed then current comics continuity. Most of the adventures for the series, like all the comics, are incompatible with the animated canon, as well as the later comics. It's one of those obscure corners that rarely gets any attention (topped only by Superman & Batman Magazine). This is the first reprinted edition.
As for the stories, it's not "our" Wonder Woman, the animated one introduced in "Secret Origins". This is the second half of the 90s John Byrne version, operating out of Gateway City, with a supporting cast of characters like Helena Sandsmark (no Cassie, unfortunately), Mike Schorr (the love interest that's been in limbo ever since Byrne left the series) and a considerably less adorable Cheetah. Also, a guest appearance by Jason Blood.
I wouldn't say I'd recommend this trade for the stories (it's nothing groundbreaking), but if you want to get a feel of what the series was like and you've got some money to spare, go for it.
