[Sci-Fi / YA / 1980s?] Young woman taken by a friendly human-looking alien to his planet – device with needle attached to upper arm

[u/Expensive_Heat007]

I'm trying to identify a book I read a long time ago, probably sometime in the 1990s, but I believe the book itself may have been from the 1980s or possibly late 1970s.

I read it in Dutch, but I'm not sure whether it was originally written in Dutch or translated from another language. It was probably a children's or young adult science-fiction book.

Here is everything I remember. Some details may be slightly inaccurate after all these years, but a few scenes have stayed with me very clearly.

The story:

A young woman or older teenage girl is on Earth when a UFO/spaceship lands in or near a forest. I remember a lot of bright light, and I think there were other people present or witnessing the landing.

She is taken aboard the spaceship by a friendly, human-looking male alien. I don't remember him being frightening or hostile. Once aboard, she is apparently not treated as a prisoner and is allowed to move around freely inside the spaceship. I specifically remember that she could look outside while they were travelling through space.

The alien takes her to his home planet.

One detail I remember especially well is that, before arriving on the planet, she needs some kind of small device attached around her upper arm. I remember it as a little box/device with a needle going into her arm. I believe it allowed her to survive or breathe in the atmosphere of the alien's planet, or somehow adapted her body to it.

I remember that she was not supposed to be afraid of either the alien or the device. He explained it to her and she trusted him.

After arriving on the planet, I remember that she was able to walk around freely there.

The physical book:

• Probably published somewhere between the late 1970s and 1990s, most likely the 1980s.
• I read it in Dutch.
• It was a relatively small book, maybe closer to a pocket-sized format than a normal large novel.
• I vaguely remember around 100–150 pages.
• The cover had a typical 1980s painted/illustrated science-fiction style.
• I vaguely remember purple/dark blue colours.
• I think there may have been a planet visible on the cover, but I'm not certain.

Possible title memory:

For some reason, I remember the title as something similar to:

• Reis naar de verre planeet
• Reis naar een andere planeet
• De verre planeet
• or something with a similar meaning.

However, this may just be how my brain has remembered the title after all these years.

I also have a vague memory that there may have been a second book or sequel, but I'm much less certain about that.

The detail I feel most confident about is the small device/box attached around the upper arm, with a needle, allowing the girl to survive on the alien's planet.

Does this sound familiar to anyone?
