Sequels to stand out debuts often struggle to advance the series plot and recapture the magic of the first book. INSURGENT isn't one of those sequels. It's as powerful or even more powerful than it's predecessor. And considering how phenomenal DIVERGENT was, that's no small compliment.One of the most inventive and action packed dystopian series ever, INSURGENT picks up almost immediately after the end of DIVERGENT.  The factions that dictate every aspect of society are in danger and all out war seems inevitable. Tris's faction has ben split as too many members have turned traitor.  Power hungry Erudite have set their sights on the Divergent, like Tris, systematically rounding them up to kill...and worse.What continues to impress me with the Divergent series is the character arcs.  They are magnificent.  Tris transformed from the almost Amish-like Abnegation member to a brave and confrontational Dauntless member so convincingly in DIVERGENT, and her transformation in INSURGENT is no less impressive.  After the tragic choice she made at the end of DIVERGENT, Tris is plagued with guilt, self recrimination, and shame.  She isolates herself even from those she cares about the most. It's heartbreaking to read. And Tris isn't the only one who evolves in the book.  Characters who I thought were villains became heroes, and characters who I thought were trustworthy became villains.  Shocking doesn't begin to describe it.The beginning of INSURGENT was a little slow and not as easy to jump into as the debut, especially since the worldbuilding isn't really recapped for readers (like me) who could have benefitted from a refresher. But once I got my bearings, and the central conflict was revealed, INSURGENT was as compulsively readable as DIVERGENT.  And the revelations at the end were almost overwhelming--in a good way--considering their implications.  Bottom line, this is a series not to be missed.  The stakes just keep getting higher and I can't wait to dive into the third book in the Divergent series when it comes out in 2013.Sexual Content:Kissing
