"If I lose myself to Lady Scarlet," Kiss repeats, pressing a finger to his mouth, "then I count on you to find me." She leans closer, her whisper close to a breath. "To bring me back to you."
His lips part slightly, his exhale brushing her skin.
"Will you promise me, Zane?"
His fingers wrap around her wrist and his lips move against her fingertip, almost like a kiss—but not quite.
"I promise," he rasps.

Separated by dark forces once more, Kiss and Zane split ways—Kiss sets out to find the Gifted One known as the Healer in order to save the dying angels, while Zane risks his life to look for Skylar and August, hoping he can convince Skylar to control her Nightmares, as well as finding and saving August from Lock's trap.

As Kiss fights both Nightmares and Lady Scarlet, she soon starts to doubt whether it's a fight she can win without losing herself forever—but Zane has promised to save her when that day comes.
And it's a promise he will never break, no matter the stakes.

But soon forgotten powers from the past appear to play a greater role than anyone could have anticipated—even the angels—forged from fire and still burning bright.

Love isn't the only thing that burns like flames.
So does the past; so does the need to survive.
