It all began with The Scream. And ended with...well, if we told you that, it wouldn’t be a mystery! But in between The Scream and The Very Surprising Ending, three friends find themselves on a scavenger hunt set up for a girl they never met, in search of a legendary ring reputed to grant wishes. Are these sleuths in school uniforms modern-day equivalents of Nancy, Harriet, or Scooby? Not really, they’re just three nice girls who decide to help out a weird lady, and end up hiding under tables, tackling word puzzles and geometry equations, and searching rather moldy storage rooms.

By sixth grade, Miranda and her best friend, Sal, know how to navigate their New York City neighborhood. They know where it's safe to go, like the local grocery store, and they know whom to avoid, like the crazy guy on the corner.

But things start to unravel. Sal gets punched by a new kid for what seems like no reason, and he shuts Miranda out of his life. The apartment key that Miranda's mom keeps hidden for emergencies is stolen. And then Miranda finds a mysterious note.

Bobby Phillips is an average 15-year-old boy. Until the morning he wakes up and can't see himself in the mirror. Not blind, not dreaming, Bobby is just plain invisible.

Then he meets Alicia. She's blind, and Bobby can't resist talking to her, trusting her.

Hank Zipzer: He's smart. He's creative. He's funny. His pencils are sharpened. His binders are bound. He wants to do well in school, he really does. He tries not to be lazy, like his parents claim he is. So why is he always getting into trouble?

Jeremy Fink has big plans for this summer with his best friend Lizzy, a notorious troublemaker (and no, he does not have a secret crush on her). He has everything he needs within a few blocks of his home, so he never has to leave his little neighborhood. And this summer, he officially becomes a teenager.

When Ari's mother died four years ago, she had two final wishes: that Ari and her older brother, Gage, would stay together always, and that Ari would go to Carter, the middle school for gifted students. So when eighteen-year-old Gage decided he could no longer live with their bossy guardian, Janna, Ari knew she had to go with him - even though she'd miss baking cookies with Janna and curling up to watch HGTV. What Ari didn't realize was that Gage didn't have an apartment yet.

As their friendship grows over a shared love of classical music, June and Tyrell confront a new housing policy that puts homeless families in danger.

Maggie Silver has never minded her unusual life. Cracking safes for the world’s premier spy organization and traveling the world with her insanely cool parents definitely beat high school and the accompanying cliques, bad lunches, and frustratingly simple locker combinations. (If it’s three digits, why bother locking it at all?) But when Maggie and her parents are sent to New York City for her first solo assignment, her world is transformed.

Greta loves her job as assistant librarian. She loves her best friend, Will, the high school civics teacher and debate coach. She even loves her mother despite her obvious disappointment that Greta is still single. Then she meets Mac in the poetry section of the library, and she is smitten. Mac is heart-stoppingly gorgeous and showers her with affection - poetic text messages, and free hot chocolate at the local café where he works. The only problem is that he seems to be a different person in his texts than in his face-to-face conversation.

I’ve been listening to my father sing for my whole life. I carry him in my pocket on my MP3 player. It’s just that we’ve never met face to face. My mother would never tell me how I came to be, or why my rock star father and I have never met. I thought it was her only secret. I was wrong. When she dies, he finally appears. Suddenly I have a first-class ticket into my father’s exclusive world. A world I don’t want any part of - not at this cost. Only three things keep me going: my a cappella singing group, a swoony blue-eyed boy named Jake, and the burning questions in my soul.

Secret passages? Check. Lab experiments that might make you lose your eyebrows (and other body parts)? Check. Classmates who are the smartest, strongest, most intimidating girls in the world? Double check.

Once there, Early starts asking questions and looking for answers. There are patterns and rhythms to what's happened, and Early might be the only one who can use them to track him down and make her way out of a very tough place.

Almost everybody who has grown up in Chicago knows about the Thorne Rooms. Housed in the Children’s Galleries of the Chicago Art Institute, they are a collection of 68 exquisitely crafted miniature rooms made in the 1930s by Mrs. James Ward Thorne. Each of the 68 rooms is designed in the style of a different historic period, and every detail is perfect, from the knobs on the doors to the candles in the candlesticks. Some might even say, the rooms are magic....
