Reckless Abandon

When Clary's mother gets married, she finds herself crushing on her step brother, Jonathan. What happens when her best friend, Jace, starts to get jealous? I HATE SUMMARIZING, BUT WHAT'S UP. AU. Clonathan in the beginning. Clace later. Rated M for SMUT/Lemons eventually, and swearing all the freaking time. Awkward internal dialogue. Hilarious. Sexual themes.
