The Lightning Rod by Brad Meltzer

Zig and Nola are back—in the hugely entertaining, highly anticipated follow-up to Brad Meltzer’s #1 New York Times bestselling thriller The Escape Artist.
What’s the one secret no one knows about you?
Archie Mint has a secret. He’s led a charmed life—he’s got a beautiful wife, two impressive kids, and a successful military career. But when he’s killed while trying to stop a robbery in his own home, his family is shattered—and then shocked when the other shoe drops. Mint’s been hiding criminal secrets none of them could have imagined.
While working on Mint’s body before his funeral, mortician “Zig” Zigarowski discovers something he was never meant to see. That telling detail leads him to Mint’s former top secret military unit and his connection to artist Nola Brown. Two years ago, Nola saved Zig’s life—so he knows better than most that she’s as volatile and dangerous as a bolt of lightning.
Following Nola’s trail, he uncovers one of the U.S. government’s most intensely guarded secrets—an undisclosed military facility that dates back to the Cold War and holds the key to something far more sinister: a hidden group willing to compromise the very safety and security of America itself.
Trouble always finds her…
She’s the lightning rod.
