Katherine McNamara's New Single 'Ember' Will Be Featured in 'Shadowhunters' Season Finale!

Clary and Jace share a tender moment in this still from tonight’s Shadowhunters season finale.

In the hour-long episode called “Beside Still Water”, Shadowhunters are divided as Alec and Isabelle battle a swarm of demons attacking the city, as Jace and Clary must head to make a final stand.

In a recent interview, Katherine McNamara revealed that her first single in a long while, “Ember”, will be on the soundtrack for the episode!

“[It's] being released after it airs on the 15th,” she announced. “I wrote ‘Ember’ just after shooting season one of Shadowhunters.”

Kat adds, “It was partially inspired by the characters in the story but mostly inspired by events that happened in my life. We all have moments where we doubt and we question who we are and what we think we’re supposed to be because something or someone or some event has caused us to second guess.”

“In spite of that, there’s always a glimmer of hope, and ember in the ashes that still burning and is ready to reignite at any moment. That is what ‘Ember’ is about�that moment of reignition.”

Shadowhunters airs TONIGHT @ 8PM ET/PT on Freeform.
