City of Forgotten Memories (Cassandra Clare fan-fiction)

Starring Elizabeth Olsen as Leena

Leena just wanted to find the person she had spent all her life looking for. She didn't need or want the Shadowhunters involving themselves, but when they did, they pulled her into a complete new perspective of life. But Alec was ordered to kill her, and he refused to go against his order direct from the Clave. Leena can't use their help with Alec hunting her, but help may not come from anyone else.

At least, not from anyone she remembers.

Based of the books by Cassandra Clare, after the Mortal Instruments and the Infernal Devices. Please note: Heavenly Fire had not come out as I wrote this, so I didn't know what happens at the end of the series. Contains spoilers for the Mortal Instruments and the Internal Devices.
