   Summary

   Three months after Alec Lightwood presented as an Omega on his eighteen birthday, his first heat arrives. As the only Omega Shadowhunter, unmated and unclaimed, what will he do?

   Please note than I do not own the characters from The Mortal Instruments or The Mortal Instruments themselves. They belong to Cassandra Clare.
