How to Read the Hilo Books
Read Hilo books #1–11 in order, from The Boy Who Crashed to Earth through The Great Space Iguana. Different friends take the lead later in the series, but the publisher keeps them in one continuous numbered story.
Hilo Presents: The Mighty begins a spinoff with different heroes and worlds. It is a next option for children who enjoy Judd Winick's storytelling, not Hilo book #12.
