“There’s something reassuring about opening a nonfiction book and knowing that all the stories and people you will read about are real; that everything between those covers is entirely factual. There’s also something exciting about opening a novel and knowing that all the stories and people you will read about inside are imaginary; in that world, there is no limit to the adventures that can take place.

But what if—just go with us for a second here—what if you could blend up a delicious bookshake to combine the very best of both of these elements?

Welcome to Two Truths and a Lie—the book series that tells you to think, not what to think!

Here’s the scoop: Every scintillating, science-packed chapter in this book contains three stories. Two of these stories are 100% true and you can believe them fully. But one of the stories . . . is not. Beware of that story! It might contain true bits, might name actual people or events or explain true concepts. But in every chapter, there will be one story that overall—its main point, direction, or idea—is fake, false, kaput.

The task set before you is simple: Read. Reflect. Research. And then pass judgment on what you have read. Is the story true or false? Fact or fake? Cross your heart or cross your fingers?

Once you think you’ve got it figured out, you can flip on over to the back of the book to check your answers. But don’t peek ahead . . . you wouldn’t want to spoil the fun, would you?

We’re not gonna lie (about this, anyway)—digging up the truth will be a challenge! But isn’t that true of most of the best things in life?

Here we go. . . .”
