The Alpha's Protection

His wolf wants to mark me. I can't let it happen.
On the run with my kids, the last thing I expect is to find my true mate. 
He's magnificent--a shifter enforcer and a human lawman.
A true protector. He wants to shield us from danger. Take care of us. 
He wants to claim me and make it forever.
But I can't let him. Not when it could cost him his life.
