Blood Promise by Richelle Mead

  Rose heads to Russia to find Dimitri and put her undead boyfriend/mentor/teacher out of his misery.  Along the way Rose meets Dimitri's family - his mother, his grandmother, and his sisters.  Siberia turns out to be a lovely place and Dimitri's family even lovelier.  Rose almost decides to stay.  But she can't.  She has a mission to accomplish.  Plus, there's still Lissa back home to worry about.  Rose also meets another spirit user who happens to be married to her dhampir guardian.  It seems that spirit users aren't as rare as everyone thought, they keep coming out of the woodwork.  Rose meets some other interesting people as well - an alchemist, her father - all people who are sure to make an appearance later in the series.

There are two more books left in the series, which I hope to finish before the end of the month.  So far this has been a very enjoyable  young adult vampire series.   Sometimes these types of series start with a bang and end with a whimper.  Hopefully this series will end as strongly as it began.
