The Blonde Who Came In from the Cold: A Second-Chance Adventure Rom-Com about Rival Spies, Thrilling Secrets, and a Mission of Survival–Perfect for Summer Reading (The Blonde Identity Series, 2)

An action-packed, second-chance rom-com about two rival spies who must join forces in order to stay alive, from New York Times bestselling author Ally Carter.
Ten years ago, they joined the CIA.
Six years ago, he left the game.
Five years ago, they fell in love.
One year ago, she ran out into the cold with absolutely no intention of ever coming back.
And two minutes ago, they woke up, bloody and bruised and handcuffed together in the dark.
They don’t know where they are. They don’t know how they got there. And they have absolutely no idea who is after them or what this nameless, faceless villain wants.
The only thing that’s clear is that, after ten years of covers and chemistry, secrets and lies, these two rival spies have been sucked into their greatest mission yet, and now they’re going to have to team up to stay alive. (If they don’t kill each other first.)
