Final GirlBook - 2017
"Kat hasn't seen the Thing since Argentina, but weird things have been happening ever since. Kat's handwriting is appearing in strange places and the film crew on P2P gets footage of two Kats. Mi Jin has a theory: it's a doppelganger. But Kat needs a solution, and fast, because whatever the Thing has become, it's lashing out at the people Kat cares about most. And what did the Thing mean when she promised Kat's mother that the old Kat would soon be gone, and the new Kat would come home... forever?"--Page  of cover.
