From publisher blurb: Mole Mechs are tiny robots, often termed nanobots, that are implanted inside a human or animal body. From the point of implantation, the Mole Mech can undertake any number of amazing and sometimes terrifying effects. Sometimes the nanobots simply bond to the host’s organs, making them stronger, faster or smarter. Other times, the Mole Mech’s nanobots make up a series of disassembled components that, when activated, manifest as astonishing external machinery. Generally speaking, the robots that make up a Mole Mech are hundreds of thousands in quantity, each no more than one micron squared in size. Due to their tiny size, the nanobots that make up a Mole Mech, when manifested, often are seen as a mass whose knitting is so small and tight they appear to be a single, solid, object.
