Sorry for the extra choppyness of this chapter, pretend it's just short scenes that will be fleshed out as I go along...I don't own HP it's JKR's I merely play. Issaline belongs to Lady Amaranth (who now has a new story posted, I'd go read it if I were you :-))

The Half-Blood Prince (age 19-20)

"But Rhiannon, they'll recognize you if you go like that!" Hermione sounded shocked.

"I don't care," Rhiannon replied, her tone flat and bitter. "I'm tired of hiding. Of pretending." Rhiannon turned away from the window and looked at the members of the Order of the Phoenix who were watching her worry in their eyes, and she realized she had just sounded a great deal like Sirius.

"Oh, don't worry. I won't do anything particularly rash. I certainly won't go looking for my dear Aunt Bella if that's what your worried about." She said it more harshly then she had meant.

Rhiannon joined Tonks as the students went up towards Hogwarts.
"See anything worth while?" she asked.
"No, you?" Tonks' manner was so different from the last time they had met, that Rhiannon felt slightly thrown off.
"Well...I didn't see Potter, and my brother looked suspiciously smug...but it could just be cause that..." Rhiannon made a sour face, "...revolting Parkinson girl had her arms wrapped around him the whole train ride..."
Tonks gave a week grin. "Well, I'll go take one last look on the train then. Why don't you go up to the School? I'll see you up there when I come in."
Rhiannon nodded, and watched Tonks board the train, and then got into one of the last carriages, which was, luckily, empty.

"They've got a new member, and Tonks wouldn't tell me who it was. All she said was that it was a witch, and that she was good at potions. She seemed to expect me to know who it was."

"You're bloody joking." Ron looked incredulous.

Hermione, however, looked smug, and Issaline grinned, and proceeded to say, "Oh, and next time you want to experiment with potions... owl me," in a flawless imitation of Rhiannon Malfoy.

"Malfoy?" Ron still looked skeptical.

"Yes, but for heavens sake, Ronald, don't say anything more about her! If it gets out that she's in the Order, she's as good as dead."

"And why's that?" Ron insisted.

"Oh really," Issaline exclaimed, "Her father's a Death Eater-"

"He's in Azkaban-"

"Her aunt is a Death Eater, not to mention a psychotic killer who'd murder Rhiannon as soon as look at her, and her brother is according to Harry, also a Death Eater. If good old Voldemort finds out that she's on our side, do you think he would say, "Oh wonderful, let her live! She's a credit to her family?" Of course not! He'd force her family to disinherit her at best, and much more likely, have them kill her personally." The two boys looked convinced, and Hermione said, "Good. Now that's clear, I want us talking about her as we did with Sirius.

Rhiannon's mind was reeling as she ran through the hall towards the shouts and flashes of light. Death Eaters at Hogwarts? How? Unless Draco or Professor Snape had let them in...She blanched at the thought of either happening. No, she thought determinedly as she hurled jinxes at the Carrows and Greyback while she sped up towards the other Order members, No! Professor Snape couldn't! Wouldn't do such a thing! NEVER. And Draco? a small part of her mind whispered that Draco would do it...had been planning on it all year...and Snape... NO she pushed the thoughts angrily away in an attempt to focus on the task at hand.
