Lamia shouldn't have died that way *spoilers*

It's a metaphor, cyberose. She's the queen of darkness, as you can hear ditch-water say. She was not defeated by heat, but rather by light.

If someone has read the book, perhaps you could explain the situation better.

That's like complaining if somebody was dropped into the sun, that they disintegrated. There is such as a thing as "too much of a good thing". The level of Shine Get that she wanted was not at all what she received, due entirely to the TRUE LOVE factor. The previous and only known fallen star beforehand was just really really happy.

It's fantasy. I know that's a cliché answer, but it can't really be explained. Just the same as the Wicked Witch of the West from The Wizard of Oz - since when does one melt into the ground from having a bucket of water chucked over them?

As Yvain tells Tristan, "I couldn't have done it without you." Although Lamia has said she wants the star healthy and glowing, I'm assuming that she's never tried to cut the heart out of one that wasn't bound, weakened, and dispirited. As for the "path" of the light, Yvain is evidently able to direct or control it to some extent because the only thing she harms is the evil witch. The witches' palace suffers no (more) damage. More importantly, recall that Yvain tells Tristan to close his eyes and hold tightly to her, suggesting there is some risk to him if he's not protected in this way. So there is some internal logic to the manner of Lamia's death, but such hairsplitting is sort of ridiculous in a story in which a rock wall separates a village in Victorian England from a magical domain called Stormhold where witches can turn men into goats and goats into men and stars can whisper warnings to their sister's protector but not to their sister herself. If you're looking for plot holes I suggest that the mystery of the whispering stars (as well as the unexpectedly brief distance from the hole in the wall to the witches' castle)is far bigger than a star on earth being able to burn a queen of darkness.

Dane's character was protecting Tristan when she glowed. So there is a logic there.

It could -beautifully, I think- be interpreted as an underlying message that says:
ultimately all dark things - whether they know it or not - seek the light, even if it kills them.
