HaBO-Thon: It Was in the High School Library?

This request comes from Keisha, who has been hunting for this book for a long time:

I'm waxing nostalgic about a romance novel published before 2007 that I read
in high school and I hope you can help me. I haven't been able to find this
particular novel on Amazon. I found one that I thought was the right book
but it turned out to be a dud, a poorly written dud. I can remember some key
plot points of the book but cannot remember the hero's name, the author's
name, or the title of the book itself. Oddly enough, I do know that the
cover involves a misty forest scene in shades of purple or blue.

The heroine is named Angela (or some variation of "angel") and the story
plays up the whole Devil & Angel, Beauty and the Beast, Phantom of the Opera
quality.

The heroine is visiting family in the country and their estate borders that
of a reclusive disfigured nobleman. The first scene between the hero and
heroine occurs in her uncle's drawing room. She enters and the curtains are
drawn, the room is in shadows. They have a tenuous first meeting where she's
all drawn to his mysteriousness and he's captivated/repulsed by her angelic
beauty (she's a blonde). I can't remember if they are forced into some kind
of arranged marriage or if they remain neighbours throughout the story. It's
been so long since I last read this! But I digress...
The hero was in some kind of accident that caused scars around one eye and
extreme photo-sensitivity. He is basically nocturnal, travelling around at
night etc. Somehow, one night the heroine is walking and discovers an
abandoned tower, which later turns out to be the hero's "secret lair" (for
lack of a better word) where he looks at the stars, broods over his
disfigured face, and how he'll never be happy or loved etc. I believe he
wears a half mask, much like Erik does in Phantom of the Opera. They
basically start meeting at this tower because the heroine is just so damn
curious and the hero secretly yearns to be loved.

The main plotline of the story involves the heroine convincing the hero that
he's not unattractive and that he shouldn't hide from the world just because
he has a few scars and photo-sensitive eyes. Resistance occurs on the hero's
part, etc etc, some objections on the part of her family (uncle and a mean
aunt?) and the hero finally decides that he loves the heroine enough to deal
with the horrified looks of the world and ventures out, with tinted
spectacles to help him see during the day. HEA. The End.

If you lovely ladies, or anyone else in your sphere of contacts, has any
idea what book I'm talking about, I would really appreciate it. If not, I'll
have to go back to my old high school and snoop through their library, which
is both creepy and embarrassing!

Does anyone recall this book?
