Allegiance (The Penton Vampire Legacy) - Susannah Sandlin

It's been more than a year since I read Omega (a series that I thought had ended).  I found myself a bit lost with this one.  I should have read Omega Force first (a separate, but not, series).  I think (in part) that's why I didn't enjoy this as much.

I thought the romance was wishy-washy.  It starts out appearing to be a Cage/Melissa pairing.  Then she and Mark make-up and she disappears from the plot line.  This just didn't do it for me.  The first 3 books in this series were so much better.
