(3) 4-6 Icebreaker series. Twelve-year-old Petrel (Icebreaker) and the stranded crew of the ancient icebreaker Oyster are reluctantly rescued by the captain of the Rampart, a giant submersible. Slowly, the two groups bond and join together to resist the fanatical, world-ruling Devouts (a.k.a. Anti-Machinists) and restore knowledge to the world. Packed with action, adventure, and memorable characters; readers will clamor for the trilogy's final installment.

(3) 4-6 Icebreaker series. When Petrel, an orphan with no place or position in an isolated ship-bound society, saves a strange boy from the ice, she unwittingly destabilizes a truce among the ship's three "territories" while also putting it in danger from a machine-hating brotherhood. Character development and sinister agendas add interest, while the broader messages about trust and friendships (lost commodities in this world) provide deeper meaning.
