About This Book
The crunch of cracked asteroid rock echoes beneath your feet as strange cosmic winds whisper secrets of the stars. Chorkle’s five watchful eyes glow softly, guiding Hollins, Becky, Nicki, and Little Gus through the eerie silence of Gelo. Together, they face fierce thyss-cats and the vast unknown, yearning for the warmth of home but discovering courage in the cold expanse.
