I love unreliable narrators too, though I don't write them particularly often - certainly not as often as you do, by the sounds of it. I think that the way you use them is awesome - I love revealing characterisation by the flaws or gaps in a person's narration. I think that having a character like Lissa, who seems like she should be unreliable but actually isn't, is an especially good twist to the whole thing.

Thanks for writing this. I love reading what other people write about their writing.
