what does this haiku mean..?

[bitter sweet rose.]

It's in a book i'm reading called betrayed. It's a House of Night novel.

the phrase is
'Alluring Priestess
Night can't cloak your scarlet dream.
Accept Desire's call.'

Think you can help? Thanks.

[yeeitsjustine]

Attractive Priestess,
You can't hide your desire for sex (sex = scarlet dream) with the night.
Give in.

[|_ () \/ |:]

is expresses deep felling of one's inner heart about the way they feel about Priestess
