Voices is the 1st novel based upon the Babylon 5 series. It is a good novel, but fans of the television series may find it uncharacteristic or possibly a bit annoying. I tried to remind myself that it was written early in the series and that many of the plot and character developments that I was aware of had not yet been explored when this book was written.
The plot concerns the Psi Corp convention being held on Babylon 5 after their original location on Mars is blown up. During the convention another bombing takes place and Talia Winters (Babylon 5's resident commercial telepath) becomes the prime suspect. Talia manages to escape from Babylon 5 as she attempts to clear her name. Talia is a fugitive being chased by Psi Corp, the military, the police and Michael Garibaldi (Security Chief on Babylon 5). Garibaldi is desperate to find her before any of the other entities, especially Psi Corp, find her.
I found the scenes on Babylon 5 at the start of the novel very good. There was a lot of humor, the interaction between Captain Sheridan, Commander Ivanova and Garibaldi were terrific. There were also some very humorous parts as Garibaldi plots to keep the telepaths from Psi Corp visiting Down Below.
However, when the book left the station it got much less interesting. The scenes on Earth while important to the plot, were not very interesting. Talia's encounter with a tribe of anglos living as Native Americans in the Native American southwest was sort of interesting, but not much was done with it.
All in all this is a good book, but not a great one. If you've never seen the television series Babylon 5, you may find it interesting. If you've seen a few episodes, you'd probably enjoy the book. If you are a die-hard fan of the series, you may like it, but try to remember that it was written early in the series run and don't expect fully fleshed out characters and situations.
