Twice Lived

West (Face) uses parallel worlds to explore the pain of coming of age in this deeply emotional fantasy. Lily and Canna alternately share one body that randomly shifts between two alternate Earths. Shifters normally settle into one or the other in their toddler years but Lily/Canna is 16 and still shifting. As each identity begins to feel uncomfortable in her own skin and the duo’s memories become increasingly blurred, they learn that if they don’t settle soon, they risk psychological fracturing. Racing against time, Lily and Canna each fight to stay in their own world yet prepare their separate families for the worst-case scenario. West does an admirable job portraying the tug-of-war between individuals as they grapple with issues of family, identity, and friendship. Readers young and old will appreciate the notes of tenderness amid the conflict and will find it difficult to choose a side. Complete with a shocking yet satisfying ending that showcases West’s cleverness, this is an impressive feat. (Feb.)
