Middle Grade and Young Adult

Building 903 by Lois Lowry (Clarion)

Hawk & Sparrow by Ayana Gray (Balzer + Bray)
A teen romantasy-mystery in a world inspired by the Gilded Age from New York Times bestseller Gray. This is a young adult story of wealthy elites with magic, a mysterious murder, and a girl who is trying to track down the truth by any means needed–even if it means pretending to be in a relationship with a wealthy industrialist she would usually have contempt for (but she might be developing feelings for instead). 352 pages, ages 14+. Read more here.
When the World Was Happy by Benjamin Alire Sáenz (S&S BFYR)
The final book from the beloved, late author of Aristotle and Dante Discover the Secrets of the Universe. A moving and timely young adult story about two siblings who must rebuild their lives after a shooting at their school. 416 pages, ages 14+. Read more here.

This Month’s Writer’s Lens: Study the Idea
As you read these new releases, pay attention not just to how the books are written, but to the ideas behind them:
- What makes the story idea interesting or compelling?
- What’s the hook, and could you describe it in a sentence or two?
- What makes the idea a good fit for its particular children’s book category?
- What makes you want to keep reading?
Studying how other authors turn simple ideas into publishable stories can help you think more critically about your own ideas, and may even spark an idea of your own.
Need help knowing if your idea is a good idea for a children’s book?
Evaluate your idea before you spend months writing it to determine whether your idea is worth developing. Take the Good Idea Test here.
