What's the Name of That Book??? discussion

I'm looking for a science fiction book I read once about a girl going into space via strange means, and ending up on this icy planet. She's saved by two beings, one who is basically Regiice, since they are a crystalline, sentient mass of ice, and the other who is not that, but whose features I do not recall.

Spoiler Warning further down!

They're traveling together and they find this massive area that's supposed to be an ocean, but it's all dried up. I don't remember a whole lot about what happens or what she's trying to do, except get home, but by the end of the book I think the planet blows up or is destroyed in some way. I think her father dies or was already dead as well, but I'm not sure.

The book's cover had a man's face i think? Overlayed with a space background. I can't remember if butterflies were on the cover as well, but I feel like there were. I read it in early to mid 2000's but the book is probably much older than that, since it had an old-timey sci-fi book feel to it.

Sci-fi is not my usual taste so I'm having a hard time finding it, anyone have ideas?

It's super weird for her to be on another planet, like space travel was not the norm in the world this book took place in.

A Wrinkle in Time?

mallizard, we encourage people to bump (only) their own threads every 30+ days. Or sooner if they remember new information.

Is this book for teens or adults?

What is her father's job? How does she learn he's in danger?
How does she travel through space?

I read the book in high school, but the memory of the cover and the way the book was formatted makes me think it's more for adults.

The father's job is... some kind of scientist, I think? It's how she ends up being able to be transported to another world. And I think he's missing? And she goes looking for him only to end up being sent through the same kind of portal or strange thing to end up in the icy planet?

I can't remember how they ended up traveling specifically, but when she gets to the icy planet she gets buried under a lot of snow and it talks a lot about slowly succumbing to hypothermia before she's dug out and rescued by the two beings that end up becoming her friends.

OH My god I remembered what it was. Heartlight by T.A. Barron.

Great! Funny what will trigger the memory. Here's a link - Heartlight by T.A. Barron.
