"12 days since Mrs. Greystone and Ms. Morales were reported missing 4 children who are determined to bring back their mothers and 2 worlds . . . Until their mother vanished, the Greystone kids -- Chess, Emma, and Finn -- knew nothing about the other world. Everything is different there. It's a mirror image, except things are wrong. Evil. Their mother tried to fix it, but she and an ally got trapped there, along with Ms. Morales, their friend Natalie's mom. Now the four kids -- brave Chess, smart Emma, kind Finn, and savvy Natalie -- are determined to rescue everyone. To do so, they have to go back: into the other world, where even telling the truth can be illegal. Chess doubts he can ever be brave enough. Despite all her brains, Emma can't seem to break the code. With everything spiraling out of control, Finn has to pretend he's okay. And for Natalie, the lies of the other world include some she wishes were actually true. What if she's gotten so used to lying she no longer knows what to believe? The second book in the Greystone Secrets series by Margaret Peterson Haddix continues the story of the Greystone kids and examines the power of the truth -- or a lie -- to alter lives, society, and even an entire reality."--.

Eleven-year-old Marin and her neighbor Charley hope that by preventing a disaster that occurred twenty years ago, they can save Charley's dad from a future of guilt and self-destructive behavior.

"The Greystone kids thought they knew. Chess has always been the protector of his younger siblings, Emma loves math, and Finn does what Finn does best -- acting silly and being adored. They've been a happy family, just the three of them and their mom. That changes when reports of three kidnapped children reach the Greystone kids, and they're shocked by the startling similarities between themselves and these complete strangers. The other kids share their same first and middle names. They're the same ages. They even have identical birthdays. Before Chess, Emma, and Finn can question their mom about it, she takes off on a sudden work trip and leaves them in the care of Ms. Morales and her daughter, Natalie. But puzzling clues left behind lead to complex codes, hidden rooms, and a dangerous secret that will turn their world upside down."--.

Told from separate viewpoints, Chess, Emma, and Finn Greystone, ages twelve, ten, and eight, investigate why their mother went missing and uncover their ties to an alternate world.
