Book excerpt: Newly widowed Harriet MacIver has just taken on her first travel writing assignment–rating an adventure cruise in the Caribbean. Add a gaggle of college students on a mini semester-at-sea voyage, a rusting hulk of a ship that misses more ports than it makes, and two deaths by poisonous butterfly, and Harriet is off and running on a hair-raising adventure. And that’s before two coeds, Kate and Carly, go missing–Carly being her boss’s daughter. Pulled into a dangerous web of bioethical intrigue, Harriet races against time. If the killer isn’t stopped, Kate and Carly will die–and that may only be the beginning of his plans for destruction. With scant clues and fewer resources, Harriet must track down the college girls–and outmaneuver a murderer who is only part of an elaborate plot of medical madness. Travel writing certainly isn’t what Harriet thought it would be. Spiked with suspense and bioethical intrigue, The Butterfly Farm invites you to solve a Caribbean puzzle with travel’s most delightful woman of mystery. From the Trade Paperback edition.
