Part 2, The Smoke: Chapters 17-22 Summary

Tally leaves the city after midnight with provisions and a long-range hoverboard provided to her by Dr. Cable. Tally follows Shay's directions, easily understanding the first part of the message but unclear about her next step. However, when Tally spots a railroad track not far from the broken roller coaster, she is able to decipher Shay's clue.

Tally travels most of the night until she reaches a bridge with a large break. Tally nearly falls off the edge of the broken bridge, but manages to lift herself up again with the hoverboard's weakening power and the wind. Tally decides to camp on the bridge, enjoying a hot meal of spaghetti Bolognese before going to sleep. When she wakes, Tally travels on, coming to a second broken bridge and what appears to be the next clue...
