The Candy Smash: Book 4 by Jacqueline Davies

 Evan believes some things (such as his poetry) are private. Jessie believes scandal makes good news.

When anonymously sent candy hearts appear in Class 4-0, self-appointed ace reporter Jessie determines to get the scoop on class crushes.

Like a modern-day Beverly Cleary, Jacqueline Davies writes with heart, humor, and honesty about family and school life for middle schoolers.
