Tom, flying the "Jenny Haniver", is intercepted on his way to Tienjing and brought to Batmunkh Gompa, where he is interrogated by Naga. Tom pleads for Naga to not use the weapon on New London, but Naga mistakes him for a "Traktionstadtsgesellschaft" spy and disbelieves him. Hester and the others arrive in Batmunkh Gompa, where Zero discovers Popjoy is dead. When Zero meets with Naga, he accuses her of being a spy, believing that London is the master of the new weapon and that Popjoy faked his death to join them. Naga has Zero beaten and detained, then orders for their forces to attack London. Pennyroyal informs Hester and Shrike of Zero's predicament, and Hester is shakily reunited with Tom, who tells her that Theo is alive and with Wren in London. With Shrike, the pair escape on the "Jenny Haniver". The Stalker Fang targets Zhan Shan, a volcano, with ODIN, triggering an eruption that will last for weeks and destroy many provinces. Tom and Hester deduce that the Stalker Fang has gone to Erdene Tezh and fly the "Jenny Haniver" there.
