Jacob Winter is a man of principle, devoted to his wife and son. But his principles are put to the test when he discovers that his wife has been having an affair with another man - with violent results - and he finds himself bailed out of jail by a mysterious woman from his past. For a man who studiously avoids sensationalism, getting caught up with Alix Callahan, fiery lesbian ethnobotanist, and her bisexual partner, a sultry Americanized rainforest girl, is a shock to the system. And when he enters Green Girls, their tropical flower shop on the coast of Maine - complete with hallucinogenic herbs and a mini-jungle full of deadly poison-arrow frogs - Jacob finds himself tumbling headlong into a heady world of strangeness he never could have imagined.
