Check out the trailer for Oldsoul by Dan Haring (Pendrell, 2012). From the promotional copy:
Jason Gouvas doesn’t want to believe he has special abilities or that he's an Oldsoul-- a vessel for the souls of people who have passed away, but the dead girl in his mind can be very persuasive.
Her name is Erin, and through her Jason is able to access the knowledge and skills of the souls within him. And with a group of power-hungry immortals bent on destroying the Oldsouls and overthrowing humanity, he's going to need them all.
