When Agent Will Trent goes undercover in Macon, his future with Sara Linton intersects with her past as a raid by Lena Adams goes bad, resulting in her husband, Sara’s stepson, being shot.  Agent Trent tries to investigate the crime, and find out the identity of the new big bad in town, while keeping his cover.  Once Sara learns the truth, can he keep his relationship intact while finding the truth?

Unseen, the seventh entry in Karin Slaughter’s Will Trent series and my eighth overall, once again crosses over Slaughter’s previous Grant County series with her current work, checking back in on Lena Adams, who was last seen in Broken, book number four.  Once again, there is a preponderance of interconnectedness within the characters in the tale, but, being a pseudo-crossover, I guess that is to be expected.  The next entry in the series, The Kept Woman, was the first one I read, so from here on out I will be current with the series.  Looks like, as of today, there are only two entries left to go.
