The last time I saw her

In this world, Dr. Charlotte "Charlie" Stone skillfully probes the twisted minds
of serial killers, the better to understand and apprehend them. In the next
world, though, her ghostly lover convicted killer Michael Garland is facing
death yet again, unless she can save his soul from oblivion by proving his
innocence. And this dead man's dead ringer may be the key. Rick Hughes
could be Michael Garland's identical twin, but Charlie suspects that behind
the handsome face lurks the murderer whose crimes Michael paid for. Now
she's determined to use her profiling talents to uncover the truth. But when
a prison break frees a gang of psychopaths, duty calls Charlie to join the
manhunt--even if it makes her a target. And if Michael wants to hold
her one last time, he must make a devil's bargain: to trade his doom for
her deliverance.
