Remember Kyle Parker? He's that kid who started the Secret Agents a few summers ago to help out his dad, and now he's back for a new adventure. Remember Lucinda Winston? Super cute, practically a genius, and completely in love with oblivious Kyle? Well, now she has a problem--a BIG problem. Or rather, her mom has a problem. See, Lucinda's mom is this totally brilliant biology professor at NYU. But something happened to Professor Winston twenty-three years ago, and now it's come back to haunt her. Lucinda's mom is suddenly so scared that she's ready to take her family and leave New York City forever. Only Kyle can't let that happen. Not when he's finally realized how cool Lucinda is, and especially not when such a perfect case for the Secret Agents falls into his lap... The Secret Agents Strike Back is the second book from Robyn Freedman Spizman and Mark Johnston about Kyle Parker and his gang of undercover friends. Filled with adventure, danger, and the sights, sounds, and smells of New York City, this is the book for anyone willing to do whatever it takes to help a friend.
