(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.

(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.

(2) 4-6 Keepers Trilogy series. In the final volume of the trilogy, Goldie, Toadspit, and Bonnie return to the city of Jewel only to find that the villainous Fugleman has made himself Lord High Protector. If the plotting and characterization falter just a little bit, the book's minor stumbles are more than compensated for by an evocative setting, a unique cast of characters, and a satisfying conclusion.

(2) 4-6 Keepers Trilogy series. On the trail of Toadspit's kidnapped sister, Goldie Roth (Museum of Thieves) must navigate a strange city during the Festival of Lies, when everything is topsy-turvy--especially the truth. Tanner's storytelling remains just as accomplished as in the first book, and the series' tantalizing mysteries deepen; a cliffhanger ending concludes the volume.
