I did not read book 1 of this series. I was not too lost, so this can be read as a stand alone, though you may understand more of the relationships if you've read book 1 of the series.

Colt shoots someone in the line of duty and while on his administrative leave pending the ruling about the shooting, heads to a tropical destination to fish with an old friend. Instead, they get drawn into an Island intrigue where we're not sure if the bad guys are after Colt, Jax, or the girl who's Jax's client. ( )
