Ghosts of the World Fair. Parisian Ghosts, #6

When the past collides with the present, everyone's secrets are at risk-including the dead's. The ghosts of Paris are gathering for a once-in-an-afterlifetime event: a recreation of the 1889 World Fair, hosted by none other than Gustave Eiffel himself. The undead ingenuity on display is impressive, but not every ghost-or whisperer-is attending with good intentions. While the ghost police, led by Sébastien's ruthless father, tighten their grip on whisperers, Sébastien and I are on a mission to expose their corruption.
But justice has its price: my family is under threat, my sister Hélène plans to betray me to the enemy, and Gaspar-my sweet hedgehog boy-is slipping further into a darkness I'm terrified I can't save him from. Everything comes undone at the World Fair. Alliances will be tested, enemies confronted, and sacrifices made. It's good to celebrate the past, but if I fail, neither the living nor the dead will have a future. Urban Fantasy with a French twist.
If you like cave-crawling adventures, hopeless romantics, and ghosts, you'll enjoy Ghosts of the World Fair, the 6th book of the Parisian Ghosts series. Travel to Paris today to attend the wondrous Exhibition Universelle of the undead.
