Sentinels of New Orleans, book 5: Belle Chasse
Suzanne Johnson2016

With the wizard-elven treaty on the verge of collapse, the preternatural world stands on the brink of war. Unless former wizard sentinel DJ Jaco manages to keep the elven leader, Quince Randolph, focused on peace and not personal matters.

With no one on the throne, Faerie is in chaos, with rival princes battling for power. The still-undead pirate, Jean Lafitte, is building his own army of misfits, and DJ—stripped of her job and hiding in the Beyond to avoid the death sentence handed down by the wizard Council of Elders—can’t get anywhere near her beloved New Orleans or her significant something-or-other, Alex.

It's time to choose sides. Friends will become enemies, enemies will become allies, and not everyone will survive. DJ and her friends will learn a hard lesson: sometimes, even the ultimate sacrifice isn’t enough.
