Velvet Eclipse

The Sun has set. The Shadow is hunting.
Mairin Cote is no longer the invisible girl from Highland Home. She is the Mourning Sun, a fugitive carrying the Sentinel's Ledger?the only list of the magical guardians standing between the world and chaos. She is running for her life, driving east into the dark, trying to warn the remaining Sentinels that their sanctuaries have been compromised.
But the enemy isn't just the Serpent Keepers who murdered her father. The true threat is the man she loves.
Mathias Auer is gone. In his place is The Weapon?a cold, lethal immortal bound by a twisted new Blood Vow to Kathryn, the resurrected Huntress. Kathryn's mission is simple: eradicate the Serpent Keepers and silence anyone who knows her secrets. That includes Mairin.
Cornered in the humid, jazz-soaked streets of New Orleans, Mairin must ally with Jules, a reckless Sentinel with a dangerous plan. As a Velvet Eclipse?a rare celestial event that dampens all protective magic?approaches, Mairin finds herself trapped in a deadly three-way war. She must evade the Serpent Keepers, outsmart the Huntress, and face the most terrifying choice of all:
To survive, she might have to kill the man who once promised to love her for eternity.
