<b>In this follow-up to the #1 bestselling thriller <i>Invisible</i>, every perfect murder looks like an accident, but as bodies start to pile up across the country, two FBI agents realize that something horrible is happening.</b><br /><br /> FBI agent Emmy Dockery is absolutely relentless. She&apos;s young and driven, and her unique skill at seeing connections others miss has brought her an impressive string of arrests.<br /><br /> But a shocking new case -- unfolding across the country -- has left her utterly baffled.<br /><br /> The victims all appear to have died by accident, and have seemingly nothing in common. But this many deaths can&apos;t be coincidence. And the killer is somehow one step ahead of every move Dockery makes. <i>How?</i><br /><br /> To FBI special agent Harrison "Books" Bookman, everyone in the FBI is a suspect -- particularly Emmy Dockery (the fact that she&apos;s his ex-fiancee doesn&apos;t make it easier).<br /><br /> But someone else is watching Dockery. Studying, learning, waiting. Until it&apos;s the perfect time to strike.
