Written on Skin (Sigil Fire #2)

Magic and mystery come to life when humans encounter the secrets of Forbidden Ink.
When a blood-for-ink trade gives Genevieve more than she bargained for, her world gets upended. A visit to Cirque Nocturne to blow off some steam is intended to give her the distraction she needs, but this tattooed beauty finds more waiting for her in the shadows than she could ever have hoped for.

The shadow world of Cirque Nocturne is not always what it seems.
Maliah is a phoenix shifter, bound to Cirque Nocturne by blood and an unbreakable vow. But when the shadows reveal a darkness more beautiful than she has ever seen, she must decide whether there is room in her heart for the one thing that could make her whole or break her completely.
