Undercover Sparks #3: Island Cruising and In Charge

By Erin Smith

Undercover Sparks #3
The third book in the Undercover Sparks teen spy series is packed with suspense, romance, and heart-racing twists in two novellas.

Island Cruising

Alexis thought balancing college life and her secret role as a YIC agent was complicated enough-until Jonathan entered the picture. Confident, unpredictable, and just as skilled, he's assigned as her partner on a mission that quickly spirals far beyond routine surveillance.

Their target: a pair of brilliant hackers with ties to a dangerous foreign regime. Their mission: infiltrate, uncover, and stop a data breach that could have devastating global consequences. But as Alexis and Jonathan dive deeper, the line between strategy and risk begins to blur-and so does the line between partnership and something more.

What starts as a calculated investigation turns into a deadly game when they're discovered and captured, forced onto a mysterious boat headed for unknown territory. Trapped with no backup and no clear escape, they must rely on each other like never before.

Trust is fragile. Secrets run deep. And one wrong move could cost them everything.
In a world of deception, danger, and undeniable attraction, survival isn't just about escaping the enemy...
It's about figuring out who you can trust-especially when your heart is on the line.

In Charge

When Chad Huntington signed up for the Youth Intelligence Circuit, he expected danger, high-stakes missions, and the chance to prove himself as a real agent. What he didn't expect? Babysitting five out-of-control kids in suburban Phoenix.

Colleen Calhoun thought her biggest problem was surviving summer with her chaotic siblings-and maybe figuring out her feelings for the mysterious (and annoyingly attractive) new "babysitter." But when Chad's carefully guarded secret slips, everything changes.

Because Chad isn't just a babysitter.
He's their only protection.

As a hidden enemy closes in and a dangerous cell begins to move, a simple assignment turns into a race for survival. Forced on the run-from museums to campgrounds to the dark of night-Chad must keep the Calhoun kids safe while staying one step ahead of an invisible threat.

Trust is tested. Secrets unravel. And Colleen quickly learns that the truth is far more dangerous than she ever imagined.
In a world where nothing is what it seems, one teenage agent is suddenly in charge...
And failure is not an option.
