The Secret of Harbor Springs — Ana Raine

Carson and his mate Tate team up with Gaven and Lily to escape Federal agents who are trying to bring them back to Hidden Oaks, a prison for shape shifting Changelings. Carson's not a shapeshifter, but he holds an unusual power over other Changelings -- a power the JIA, the Federal task force charged with rounding up Changelings, will go to any ends to make their own.

Tate knows Carson is his true mate, but Carson soon realizes there will never be a normal for Tate -- the JIA will never stop hunting them as long as he's with Tate. When Lily's friend begs for their help rescuing her mate from the Harbor Springs, a prison for Changelings, Carson must decide whether to protect Tate or stand up to the JIA and fight for his kind.
