I Spy (Spy Another Day #1)
Jordan McCollum

It worked for a year, keeping Danny in the dark, keeping him away from danger, keeping her secrets. And then Talia finally catches a hot case: Fyodor Timofeyev. Russian. Aerospace executive. Possible spy?
She can make this work, too--until Danny needs her at the same time her country does. And when Fyodor targets Danny? Suddenly her schedule isn't the only thing suffering. Now to save her country and her secrets, Talia must sacrifice the man she loves.
