I read a book in 6th grade for school and I can't remember the title. It involved people living under domes on the moon. A couple of kids ended up stealing/taking a key that took them outside the dome to another dome by some sort of vehicle. I only remember them being in a weird but beautiful alienish garden.

  • Hi, welcome to SF&F! What year were you in 6th grade? You should review the suggestions for good story-id questions in case they help you recall any more details you can edit into your question.

    How long ago were you in 6th grade? 5 years? 10 years? 25 years? 50 years?

That could be The Lotus Caves by John Christopher, 1969.

The plot of The Lotus Caves seems to match the plot points outlined in the question - two YA's take an unauthorised joyride after stealing access to a moon-buggy, they eventually discover a cave system (not another dome, which is a discrepancy) made habitable by an alien plant that forms an artificial ecosystem.

    Assuming this is correct (which it almost certainly is), this is a dupe of scifi.stackexchange.com/questions/200422/…

    The discrepancy mentioned in the answer above is due to them first visiting the dome of the original moonbase, where they discover a clue to the disappearance of one of the original astronauts. When they follow the directions found in an old notebook they find the caves. Jul 30, 2020 at 23:46

It it "Emlyn's Moon"?

In that book, set in Wales, a girl called Nia and a boy called Emlyn set off to find his mother and brother who he suspects are on the moon, in the first book of the trilogy, The Snow Spider, Gwyn's sister comes back but returns to where Emylyn's mam and dad are.
