I've found this series (Slave Empire - I've read the first two) a little different from the other books. It seems more scifi, I guess, than... whatever genre the others fall into. I wasn't fond of it.
The writing is, as always, very good, and lots of what should no doubt be exciting things happen, but there is little interaction between the two main characters. What there is a lot of is interminable descriptions of ships and weapons outer spacey stuff and probably other stuff, too, that I just don't remember. Or that I skipped over. The underlying story is interesting but... well, maybe I just wasn't in the mood for this sort of presentation of it, or something.
But then, the first book was setting things up so I went ahead and bought the second book -- where, again, there was little interaction between the main characters and lots and lots of describing of the innards of a living ship. And other stuff. A lot of which I skipped over. Real interaction between the two main characters comes only at the end of the second book and then, whoops! It's time to buy the third. I'm not going to, though.
For the first time, ever, reading a TC Southwell book, I was bored! Gasp.
Others found this series fascinating, as the reviews will attest, but if you are looking to get delightfully ensnared in Ms. Southwell's web of "gotta keep reading, have to know, oh my gosh I love these characters, where is the next book!?" type of reading experience, I would go for one of the other series of books.
