Only the Good Spy Young

I just finished Only the Good Spy Young by Ally Carter, the 4th book in her Gallagher Girls series.  This is what I classify as my guilty-pleasure-flush-reading - so of course I enjoyed it.  For the most part it is more of the same, but the plot did take a few interesting twists that were exciting and really made me want the next book to come out so I could get some answers!  If you like a nice quick read of the young adult variety about a high school girl going to a secret spy school but still having to deal with the usual teen dramas, like gossip, boys, clothes, friends and lip-gloss - then this is the series for you!
