I've only read her Halo work, and thoroughly enjoyed it. Need to pick up a Star Wars work. And suggestions?
Her Star wars Republic Commando series (which starts with the book Hard Contact) are my favorite Star wars stories, period (including every other book and comic I've read and all the movies). Technically a spinoff of the Republic Commando game, but the specific clones from that are just side characters in the book series and you don't have to know anything about the game (I didn't). Its very much a love it or hate it series. To me, it humanized the clones in a way the prequels and even TCW cartoon mostly failed to do and many of my favorite SW characters come from this series.
As long as someone doesn't consider the Jedi above reproach (the jedi aren't all that revered throughout most of the series, which isn't the norm for books featuring them I've found but I like the take on it here), and is fine with a warrior culture thing (the mandalorians are a big part of the book series, and I love them even though this version got removed from canon before Disney bought it by the lame TCW cartoon version of mandalorians). The book has many characters but it does a good job of handling all of them. Its set up at the start following a group of clone commandos, who are more skilled and do more complicated jobs then the average clone soldier. traviss does a good job with the combat/soldier elements of the book, just like she does with all the other stuff in my opinion.
Definitely worth a look, although I don't think my recommendation carries much weight
