What if rainbows were people from the future traveling in time?

10-year-old Arco lives in a far future. During his first flight in his rainbow suit, he loses control and falls into the past. Iris, a girl his age from 2075, comes to his rescue and tries by all means to help send him back to his era.
Arco keeps every mind human — it fights its subject at zero distance. The story fights on E8/E7 of the E0–E14 reality ladder, compressing climate, technology, time, environment, survival.
