Parasitic - the outbreak worsens in Madness Chronicles 2

The second book picks up right where the first one left off with things seemingly settled down aboard the cruise ship Intrepid but with a flock of infected birds headed their way. The ship has come to grips with the fact that animals all around the world have become violent and after finally containing their own pet related issues they are starting to think that being at sea is going to be a real advantage. Then the birds attack and they come to the realization that the rage disease not only turns animals violent but it can also infect humans. These humans come to be known as Parasitics and they are just as bloodthirsty as their animal counterparts. Now being aboard that cruise ship isn't quite the advantage they thought it might be.
