When middle school puzzle master Sam and history wiz Martina win a contest for a summer trip across the US, they discover they've been drafted into something vastly more extraordinary. Joining another kid on the trip, Theo, a descendant of George Washington himself, they must follow clues to find seven keys left behind by the Founding Fathers. Together the keys unlock Benjamin Franklin's greatest invention—a secret weapon intended to defend the country. Each key is hidden in a unique location around the U.S., protected with puzzles, riddles, and traps. This has kept the weapon safe . . . until now! Gideon Arnold, a dangerous descendant of the infamous Benedict Arnold, is on the chase. In competition with Arnold and his thugs to reach the artifacts first, Sam, Martina, Theo, and readers must use their wits to solve ingenious puzzles, escape death-by-booby-trap, and, by the end of the series, save our nation by uncovering many of its greatest secrets.

"My plan: Get into the city. Get Nadia. Find a way out. Simple."A week ago, seventeen-year-old Lela Santos's best friend, Nadia, killed herself. Today, thanks to a farewell ritual gone awry, Lela is standing in paradise, looking upon a vast gated city in the distance – hell. No one willingly walks through the Suicide Gates, into a place smothered in darkness and infested with depraved creatures. But Lela isn't just anyone – she's determined to save her best friend's soul, even if it means sacrificing her eternal afterlife. As Lela struggles to find Nadia, she's captured by the Guards, enormous, not-quite-human creatures that patrol the dark city's endless streets. Their all-too-human leader, Malachi, is unlike them in every way except one: his deadly efficiency. When he meets Lela, Malachi forms his own plan: get her out of the city, even if it means she must leave Nadia behind. Malachi knows something Lela doesn't – the dark city isn't the worst place Lela could end up, and he will stop at nothing to keep her from that fate.
