Lady Renegades by Rachel Hawkins, 264 pages

Just as Harper Price starts to come to terms with her role as David Stark's battle-ready Paladin, protector, and girlfriend, her world goes crazy all over again. Overwhelmed by his Oracle powers, David flees Pine Grove and starts turning teenage girls into Paladins-and these young ladies seem to think that Harper is the enemy David needs protecting from. Ordinarily, Harper would be able to fight off any Paladin who comes her way, but her powers have been dwindling since David left town...which means her life is on the line yet again.
This is the finale to this trilogy. It's been a fun, light read.
