High Tide in Tucson: Essays from Now or Never is a 1995 book of 25 essays by author Barbara Kingsolver exploring ideas such as family, community, ecology and social consciousness.[1] It is titled after the first essay, in which she realizes that a hermit crab she accidentally brought home while beachcombing in the Bahamas still times its activity to the rise and fall of the tides, even in an aquarium in Tucson, Arizona.[2] The crab is a metaphor for a situation in her own life.
