Grabbing at seat backs had bled off only a little of their relative speed, and Shade hit the door at seventy miles an hour. She took the impact in her back and felt her chitin armor snap, crushed like a cockroach under a boot. Her head smashed into steel and the thick glass window, cracking her skull like a dropped cantaloupe.

The impact smashed the door open, and Shade plowed into the next door at a mere fifty miles an hour. Her hands were torn, some fingers ripped off and spraying blood, her back broken, her head caved in. She was reduced to a bloody mess of bone and chitin armor and blood.

The impact went: Shade, Armo, Francis, Dekka, and the shell.

Armo, Dekka, Francis, and the shell survived.

Shade looked like a lobster that had been cracked open and torn apart with a fork.

“Oh, God! Shade! Shade!”

Shade Darby looked far too much like a huge grasshopper that had been stepped on. It was impossible even to make sense of the lower half of her body. Bones, strips of chitin cracked like lobster shell, pink flesh protruding, and ripped arteries that pumped blood far too fast.

Dekka shot a look forward. The shell lay in the aisle, rolling sluggishly back and forth. Red numbers read 00:24 . . . 00:23 . . .

Dekka had to climb over the last row of seats to get to Shade, and she knelt over her and yelled, as she had with Armo, “De-morph, Shade, de-morph!” Again and again.

[...]

Shade had de-morphed, returned to her human form, alive and uninjured—harm suffered in morph was repaired by de-morphing, so long as the human form had not been injured.
