There is an organization of telepaths of varying strengths. The strongest are the leaders, the council and enforcers.
MC is a teen boy, I think he lives with Aunt and Uncle. Mom and Dad are missing and he finds his mother's powers have been blocked and she has been given to his father, but there is a reversal and she gains control? Towards the end there is a big fight for control, a slave auction, big mansion....
Rind any bells for anyone?
