Help me find this singer from 2008ish

I'm looking for a Christian singer/songwriter whose music I downloaded from their website in around 2008 and have since lost. It was sung by a woman, guitar and drums, and generally had a driving rhythm.

One song went "...horse and rider you have hurled into the sea. And you reign forever, yes you reign forever, Lord you reign forever on high x2".

I think the same author also wrote a song with the lyrics "The morning star, my sword and shield, lily of the valley, my living word..."

I don't remember the rest of the lyrics. A couple more half-remembered songs:

"the truth of your word says that I am forgiven. The truth of your word says that I am set free. ... The truth of your word says you're Living in me. You see me through the blood of the lamb. Clothed in his righteousness it's by grace that I am standing here, knowing I'm forgiven".

And yet another song goes "clap your hands all you people, shout to God with shouts of joy. How awesome is the lord most high, the great king over all the earth"

Any ideas, anyone? I think her name might have been Carol, but I'm not 100% on that
