Yes, to both - Hellspark first years ago (and now I own it in three different editions), and Mirabile last year when it came out in ebook. The short story collection represented above came out in ebook at the same time, but I generally take longer to get around to short story collections than I do to novels.

(I've also read her Star Trek novel, which I didn't like so much, possibly because I felt like I'd seen some of the best bits already in Hellspark, and also because her original guest star character was such an accomplished limelight stealer that Kirk and co. ended up feeling like guest stars in their own book.)
