A Klingon novel by K'Ratak which Worf gives to Data as a parting present in The Measure of a Man, when the android has resigned from Starfleet rather than be dismantled.
The Dream of the Fire is a novel by the Klingon writer K'Ratak. It appears in the second-season episode The Measure of a Man, set in 2365.
Commander Bruce Maddox has obtained orders to disassemble Data for study, and Data resigns his commission to avoid the procedure. His shipmates hold a small farewell gathering at which he unwraps their gifts, and Worf's is a copy of the book. Worf remarks that the novel reached its full stature in Klingon hands, and Katherine Pulaski cheerfully disagrees.
The gift is a small sign of the regard between the ship's two outsiders. Data never has to leave: the hearing that follows, argued by Picard before Captain Phillipa Louvois, rules that he is not Starfleet property and has the right to choose.
