The Brass Giant — Brooke Johnson

Sometimes, even the most unlikely person can change the world

Seventeen-year-old Petra Wade, self-taught clockwork engineer, wants nothing more than to become a certified member of the Guild, an impossible dream for a lowly shop girl. Still, she refuses to give up and tinkers with any machine she can get her hands on, in between working and babysitting her foster siblings.

When Emmerich Goss -- handsome, privileged, and newly recruited into the Guild -- needs help designing a new clockwork system for a top-secret automaton, it seems Petra has finally found the opportunity she's been waiting for. But if her involvement on the project is discovered, Emmerich will be marked for treason, and a far more dire fate will await Petra.

Working together in secret, they build the clockwork giant, but as the deadline for its completion nears, Petra discovers a sinister conspiracy from within the Guild council…and their automaton is just the beginning.
