“A caveman walks into a bookstore” may sound like the beginning of a joke… but they are legitimate struggles for our era-hopping characters out of sync with Father Time. They may be trained in military strategy or to scribe Egyptian hieroglyphics on papyrus, but these skills won’t help one bit in surviving the cut-throat modern world of schools, malls, and MTRs. Will our time travellers be able to find their way back? Or will they forge ahead, here and now, with the rest of us? Either way, this is history in the making.
