Deryn Sharp Timeline and Summary

Deryn Sharp shows up at Wormwood Scrubs to take the Air Service entrance exam; as part of the exam, Deryn volunteers to go up in a Huxley.
The Huxley gets caught in a storm, and Deryn is rescued by the Leviathan—and because the ship is bound elsewhere, Deryn finishes her training on board.
When the Leviathan lands in the middle of London to pick up Dr. Barlow, Deryn earns her place as one of only two midshipmen left aboard.
Deryn fights in the first battle when, after Britain enters the war, ten German aircraft attack.
After Alek stumbles into her as part of the Leviathan's wreckage, Deryn takes him prisoner and manages to stave off violence between the Leviathan's crew and Alek's friends.
Deryn fights two German zeppelins from an Austrian walker, proving she's a good soldier no matter the ship.
Deryn becomes good friends with Alek, affirming their friendship by refusing to tell Captain Hobbes who Alek really is.
