Concealed — Kate Serine

As the only female initiate of the elite undercover society, the Dark Alliance, former FBI agent Madeleine Blake has a lot to prove -- especially to her former lover, Alliance operative Jack Grayson.

Yet when a mission ends in tragedy, Maddie's ready to walk away from the Alliance -- and Jack -- forever. That is, until Jack's cover is blown, putting his life in danger and making it impossible for Maddie to deny her true feelings…

Before he met Maddie, Jack Grayson thought happiness was impossible for a man like him. After all, he has a price on his head that requires him to live in the shadows, concealed from everyone and everything he cares about. But now that they're on the run for their lives and Jack has Maddie in his arms again, he realizes their love is the only thing in his life that's real. And this time, there's no way in hell he's letting it slip away…
