This is the first book in the Rampart Worlds series. It works well as a stand-alone novel.
I found the book entertaining. It's fun light SF. It starts with a feel similar to a mystery. As a whole, it's more interstellar corporate intrigue and adventure than "mystery".
The son of one of an interstellar company's owners chooses a career regulating business rather than running one. He's framed by a company and ends up living in exile on a faraway planet having a small business with a recreational boat for tourists - until someone tries to kill him. His father visits him during his recovery and asks him to help find his sister who has gone missing. Corporate intrigue and questions about alien connections build up.
I'm generally the kind of reader who prefers more believability (both in science and otherwise). Although I found the book entertaining, other readers who care about how believable a book is may appreciate me noting some issues in that regard. As is fairly common in adventure fiction, the capabilities of the protagonist can be incredible. There are also scientific plausibility issues. Excluding the use of FTL which is nearly universal in SF, the clearest science issue is genetic engineering which combines genetic material from species which had entirely independent evolution in widely distant star systems. So, I would not recommend reading this when you are looking for something more serious.
