From the Shadows. Agents of STARR

Mia Jefferson thought she had the perfect life: a career as a best-selling romance author, a husband who loved her, and her rescue pittie, Cookie. Then her husband was murdered in their backyard, and the secret life he led came to light. Known on the dark web as Black Dragon, he double-crossed the wrong people and paid for it in blood. After surviving an attack that killed most of his squad, Carson Daniels gave up everything to join STARR, including his identity.
He had only one regret: Mia, the girl he'd loved since he was seven, thought he was dead. Now known only as Smoke, he will do whatever it takes to save the innocent. After receiving his most important assignment as an agent of STARR - protecting Mia and finding the information left by her hacker husband - will his identity, and his life, be compromised when those old feelings resurface, or will they finally find the happiness they both deserve?
