Elara is vengeful.

Enzo is trapped between the realms of life and death and her enemy has vanished, taking her love’s only connection to the waking world with him. But there is a darker force at play, one that even Ariete, King of the Stars, is afraid of. On the run with enemies at every turn, Elara must enlist friends, old and new, and learn to control her almighty powers if she has any hope of saving her soulmate.

Whatever happens, there is one thing she is certain of:STARS WILL FALL.
