In this sequel to the New York Times best-selling Charlie Thorne and the Last Equation - which number New York Times best-selling author Chris Grabenstein called “a real page-burner” - Charlie searches for Charles Darwin’s hidden treasure in South America. Charlie Thorne is a genius. Charlie Thorne is a fugitive. Charlie Thorne isn’t even 13. 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 10 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?

In the seventh novel in New York Times best-selling Stuart Gibbs’s FunJungle series, Teddy Fitzroy returns as FunJungle’s resident sleuth to solve the disappearances of endangered bison and an irreplaceable necklace. Teddy Fitzroy, his family, and some other FunJungle employees have been invited to visit a bison ranch just outside Yellowstone National Park that FunJungle’s owner, J.J. McCracken, is considering purchasing. But as usual, trouble isn’t far behind. The ranch’s endangered bison have been mysteriously disappearing. Then a massive local grizzly bear named Sasquatch breaks into the house, causing chaos. In the aftermath, Kandace McCracken discovers that her exceptionally expensive sapphire necklace has vanished. Was it stolen? Or did Sasquatch eat it? (And if so, can it be recovered?) And what’s been happening to the bison? With over a dozen suspects, it’s up to Teddy to detangle this hairy situation, before his family or friends - or any more expensive objects - become dinner.
