Amazing!

This book was really good. I'm a huge fan of science fiction, and I like math a lot, so if you fit into these categories, you should read it too.

What's the story?

At the start of THE STRANGERS, the Greystone kids -- Chess, Emma, and Finn -- see their mom react to news of a kidnapping involving kids with similar names and ages as themselves. Before they can question her, she suddenly leaves on a business trip, leaving them in the care of a neighbor, Ms. Morales, and her teen daughter Natalie. The Greystone kids notice strange clues left behind by their mom, and when they suspect she's in danger, their quest to solve these puzzles grows ever more urgent. Soon they're exploring a mysterious passageway beneath their house and wondering where they'll end up.

Is it any good?

Wondering what might have been fuels the plots of many science fiction novels, but this book keeps the alternate-world premise feeling fresh and exciting. The Greystone kids are a well-realized set of siblings, immediately recognizable as types, but with plenty of other layers to keep them interesting. Author Margaret Peterson Haddix sets up a captivating series of puzzles regarding their mother's whereabouts, and the solutions are riveting and smart. Suspenseful all the way through, The Strangers ends on a cliffhanger, and young readers will be clamoring for more.
