Moon Shimmers (Sisters of the Moon / The Otherworld Series, #19)

We're the D'Artigo sisters: savvy half-human, half-Fae operatives for the Otherworld Intelligence Agency. My sister Delilah is a two-faced werecat and a Death Maiden. Menolly is a vampire married to a gorgeous werepuma and a vampire prince. And me? I'm Camille, a Moon Witch married to three gorgeous husbands, and I'm about to ascend to the throne of Dusk & Twilight. But the path to the throne lies through a labyrinth of dangers, which I must face alone...

Before I can fulfill my destiny to become the Queen of Dusk & Twilight, I must seek out the Keraastar Diamond. But to find the magical gem and take control over the Keraastar Knights, I must venture back to Otherworld, deep into the treacherous Tygerian Mountains. Once there, I face a magical trial by fire. If I fail, the chance to stop Shadow Wing will fade with me. If I succeed, my life will forever change. And I'm not certain which prospect frightens me the most.
