""Near the top most deck of an interstellar generation ship, Dorothy Gentleman wakes up in a body that isn't hers--just as someone else is found murdered. As one of the ship's detectives, Dorothy usually delights in unraveling the schemes on board the Fair weather, but when she finds that someone is not only killing bodies, but purposefully deleting minds from the Library, she realizes something even more sinister is afoot. Dorothy suspects the misfortune is partly the fault of her feckless nephew Ruthie who, despite his brilliance as a programmer, leaves chaos in his cheerful wake. Or perhaps the sultry yarn store proprieter--and ex-girlfriend of the body Dorothy is currently inhabiting--knows more than she's letting on. Whatever it is, Dorothy intends to solve this case. Because someone has done the impossible and found a way to make murder on the Fairweather a very permanent state indeed. A mastermind may be at work--and if so, they've had three hundred years to perfect their schemes..."--Publisher description
