The Demigod Files
by Rick Riordan
Middle grade · ages 9–12 · 720L · 2010
A bridge book that deepens the Percy Jackson universe without advancing the main plot — best read after Book 1, not as entry point; the three novellas reward fans but don't standalone.
Tristan Strong Punches a Hole in the Sky
by Kwame Mbalia
Middle grade · ages 8–12 · 780L · 2019
A genuinely moving adventure that teaches Black history through myth and folklore rather than lecture; Tristan's arc is believable and the supporting cast of tricksters and ancestors is unforgettable.
The Scarecrow of Oz
by L. Frank Baum
Middle grade · ages 8–12 · 780L · 2022
A solid Oz adventure that leans on Baum's gift for whimsy and ensemble chemistry; less intricate than *Wonderful Wizard*, but the episodic quest keeps pages turning.
