The place and time
Deep space and on the jungle resort type planet Dantaralon. I imagine it's in the far future in our timeline, but it could be an alternate universe.
The suspension of disbelief
Interstellar travel exists! Humans and other races are in space, and some aliens are at war with humans.
Meg Antille is working on a cruise ship, and Simon "Red" Thomsill, recently retired soldier, has gotten a job aboard it to get to know her better. During a stopover on a nature preserve planet, things go ill. The ranger station is deserted, the big dangerous wild animals aren't being kept away as they should, and then the ships take off without their passengers. Simon, Meg, and the other passengers get pursued through the jungle by pirates and have to find a way to get off-planet safely. During the journey, Meg and Red develop a mutual respect to go with their mutual attraction.
