When Tessa unexpectedly acquires a mirror and a journal from her long-dead grandmother, Suvi Markku, she is thrust into danger from alien creatures called Polydactyls. She turns for help to her neighbor Jakob Faircrow, but she finds his smug arrogance infuriating. Jakob and Tessa must put aside their differences long enough to discover why Suvi hid the mirror and why the Polys want it. The journal provides vital clues to Suvi's past life in Severnessa with Jakob's twin brother Lut -- a life that will shortly intersect with Tessa's, when a magic gateway blends past and present, and brings the two women face to face with the creator of the Polydactyls. Wintermoon Ice is a spellbinding tale of twos: two cites, two times, two brothers and two women, who must save their world from an unspeakable terror. It is the first book of the "Sons of the Mariner" series.
