Hmm, yes, it's not obvious here because it's an excerpt (and something I hadn't thought about). When you read the book you'll find that Steve McLeary is working undercover as Simon Delamer -- at this point Anis is unaware of this so she thinks of him as Simon.
The name change is intentional, but I should really make it clearer why.
When I get The Universe up and running I'll have details about the various books in series in there. That should help.
Once again thanks for the comment, and for brightening up my day .
