Charlie Thorne is a genius.
Charlie Thorne is a fugitive.
Charlie Thorne isn’t even thirteen.
After saving the world, Charlie is ready to take it easy in the Galapagos Islands. That is, until she’s approached by the mysterious Esmeralda Castle, who has a code she knows only Charlie can decipher.
In 1835, Charles Darwin diverted his ship’s journey so he could spend ten months in South America on a secret solo expedition. When he returned, he carried a treasure that inspired both awe and terror in his crew. Afterward, it vanished, never to be seen again…
But Darwin left a trail of clues behind for those brave and clever enough to search for it.
Enter Charlie Thorne.
In a daring adventure that takes her across South America, Charlie must crack Darwin’s 200-year-old clues to track down his mysterious discovery—and stay ahead of the formidable lineup of enemies who are hot on her tail.
When an ancient hidden treasure is at stake, people will do anything to find it first. Charlie may be a genius, but is she smart enough to know who she can trust?
And if you haven’t read the first book, Charlie Thorne and the Last Equation is now in paperback!
“Gibbs deftly pens an Alex Rider–level adventure with this series starter… The plot moves at breakneck speed from start to literal cliffhanger finish. Charlie is a wildly entertaining protagonist whose intelligence is balanced by normal preteen rebellion. It doesn’t take a theoretical physicist to predict that this series will be popular.” — Booklist
“An adrenaline-charged thriller… Charlie is a terrific hero—outrageously smart, courageous, and still believable as a kid. After this explosive start, young readers will eagerly await her next adventure.” — Publisher’s Weekly

Teddy is all set for a campout at his friend Sage’s family ranch—but then Sage gets terrible news: The skull of a rare dinosaur that was being excavated on his property has mysteriously vanished overnight, even though it weighed 500 pounds. Not a single footprint has been left behind. Since the dinosaur was top secret, the police don’t believe anyone outside the dig could have stolen it.
A T-rex skull can sell for millions of dollars, and everyone is a suspect—including J.J. McCracken, the owner of FunJungle.
Meanwhile, Teddy’s old foes, the Barksdale twins, have gotten into trouble with an illegally purchased anaconda, and Teddy’s girlfriend Summer wants to find out who’s behind the local trade in black market reptiles. The two cases will drag Teddy into more danger and chaos than ever before, in this mystery that’s stranger than fiction.
