Accusations

Accusations, the second Babylon 5 novel, focuses primarily on Ivanova and Garibaldi (despite his prominence on the cover, G'kar doesn't get much attention). The plot concerns an old friend of Ivanova who gets murdered after coming to Babylon 5 to deliver an important message. Ivanova gets framed for the murder and her and Garibaldi have to figure out how it all ties into frequent raider attacks on incoming shipments of a rare metal.
Plot-wise, this is fairly standard stuff (indeed, the framing of a character for a crime they didn't commit was used in the first B5 novel). Accusations is well-written, however, with good characterization and a few twists. It's not the best book ever, but it's worth reading.
