A. Invisible Cosmic Zebras are those invisible "friends" in your life (chronic pain, an invisible illness, syndrome, disease or injury) that you have come to acknowledge and accept as lifelong companions.
Invisible Cosmic Zebras are unique and different from each other and nobody knows exactly what they look like because they are invisible.
Invisible Cosmic Zebras frequently hang out with cosmic creatures (like the ones in the book) who can assist in "taming the zebra" (managing an illness).
These cosmic creatures also help to bring hope, levity and love to those dealing with invisible (and sometimes lifelong and incurable) medical conditions.
