Someone just killed Tanis Richards and replaced her with an Infiltrator Chameleon.
While finally getting some much-needed shore leave on Mars, Tanis gets a message from Harm Ellis with instructions to go to Ceres and hunt for a missing operative . . . except she never makes it.
At least, that's what she'd like her would-be killers to think.
With Darla's help, Tanis goes deep undercover, tracking the Infiltrator Chameleon from world to world, only to discover that it intends to kill a head of state in her name.
Now Tanis must race against the clock to keep from becoming the most wanted criminal in the Sol System.
