Dazzling to behold, Gemworld is one of the wonders of the Federation: an artificial world composed entirely of crystal, its atmosphere held in place by a sophisticated network of force fields. Home to a half dozen different sentient races, this singular world is a low-gravity playpen of mammoth spires, endless fractal staircases, gemstone arcs, and dazzling prisms, oil carefully nurtured by the planet's many inhabitants -- until now. Lieutenant Melora Pozlor, who previously served on Deep Space Nine™, is currently stationed aboard the Starship Enterprise™ where an urgent telepathic summons alerts her to the danger threatening her homeworld. The crystals that once sheltered her people, and several other alien species, are now growing at a vastly accelerated and uncontrollable rate, wreaking havoc throughout the planet. Captain Picard orders the Enterprise on a rescue mission to Gemworld, but they arrive to find a world in chaos -- and an unexpected menace that traps the crew of the Enterprise along with the fragile civilization they hoped to save!

Lieutenant Melora Pazlar, first seen in the Deep Space Nine episode that bears her name (Melora), is the only Elaysian in Starfleet. Stationed on board the USS Enterprise, six years after her short-lived romance with Dr Bashir, she receives a desperate call for help from her crystalline, multi-species homeworld. When subspace contact fails, Captain Picard sends the Enterprise to investigate, only to find the ship nearly torn apart by a dimensional rift and stranded, badly damaged, below the shields that protect the carefully constructed planet. With both escape and rescue impossible, Picard and crew set out to discover the cause of the rift and the strange, cancerous growth in the crystal choking the planet itself. A Federation ship attempts to reach the Enterprise but is destroyed, and when thoron radiation threatens to kill the crew, all signs on the planet point to sabotage...

Amaya, princess of House Amethyst in Gemworld, and her brother love magical pranks. But when one goes much too far, her parents ground the young royal…to Earth! They hope a week in the mundane world teaches her that magic is a privilege…and maybe washing dishes by hand will help her realize that the palace servants should be respected. Three years later, “Amy” has settled into middle school and ordinary life. She doesn’t remember any other home. So when a prince of the realm brings her back to Gemworld and restores her magical destiny, how will she cope?

To save the dying Gemworld and free the Enterprise from the lethal grip of the singularity which has trapped it there, Picard and his crew must disable the artifical shell which holds the planet's atmostphere intact. But to safeguard the shell - since the planet could not survive without it - it cannot be shut down without six clearance keys. One key is in the possession of each of the planet's distinct and often reclusive species, and travel on the crumbling, disintegrating surface is nearly impossible. A religious sect views the shell as a holy object and will stop Picard from tampering with it - at any cost. And when all the keys are gathered and a mysterious murder is solved, the responsible party is discovered to be the planet itelf!

Sparkling like a three-dimensional snowflake in the depths of space, Gernworld once was one of the Federation's greatest marvels. Six different alien races coexisted peacefully on an artificial world composed entirely of crystal -- until the very substance of Gemworld began to multiply out of control, tearing the world apart. Now the entire planet -- and the Starship Enterprise™ as well-faces total destruction. The only way to stop the disaster is to turn off the vast network of force fields holding Gemworld's atmosphere in place, but to do so will require the cooperation of each of the planet's half dozen alien civilizations, one of which sabotaged Gemworld in the first place. With time running out, Captain Picard and his crew, including a lovestruck Lieutenant Barclay, must embark on a hazardous trek across the dying planet to find and unite the chief engineers from many strange and exotic races -- while watching out for a mass murderer determined to destroy a world!
