The Angel and the SEAL by Petie McCarty

The Angel and the SEAL . . . a cozy mystery with romantic suspense from the Mystery Angel Romances series. An angel hidden in every book waiting for you to figure out who . . .
Navy SEAL Sean MacKay’s teammate is murdered after stealing a deadly nerve-gas formula from Syrian terrorists. Naval Intelligence believes MacKay’s teammate was a traitor and shipped the stolen formula to his sister in the states for safekeeping. MacKay is given orders to find the sister before the terrorists do and to retrieve the stolen formula at all costs.
Foreclosure looms for Cory Rigatero as she fights to keep her rustic resort near Mt. St. Helens afloat after her brother deserted her to join the SEAL Teams. Cory’s whole world dives into a tailspin when Sean MacKay shows up at her resort with the news of her brother’s death and the wild suspicion her brother may have sent her traitorous classified documents. No way will Cory trust MacKay—the man who once seduced her and then vanished into the night without a trace.
