Star Trek: S.C.E.: Paradise Interrupted

STARFLEET CORPS OF ENGINEERS
For centuries, Risa has been the garden spot of the Alpha Quadrant, the place to go for rest, relaxation, and recreation. When the S.C.E. crew of the U.S.S. da Vinci learn their latest assignment is to Risa, they expect to find themselves in paradise.

But paradise isn't what it used to be. Something is draining power from the complex weather systems that keep the planet pleasant, and if the S.C.E. doesn't determine the cause soon, Risa as they know it will cease to exist forever!
