Books in the Nocturne Symphony series

What's more frightening: The mask? Or the reason it's worn? Forced to flee her lover, the witch Wren Nocturne knows she still owes a debt. She must exact vengeance for those who resurrected her. Alone, and masquerading as an abused Firefly, she struggles to satisfy the blood curse threatening to tear her soul apart. With nightmarish beasts blocking her way, Wren's search becomes a cat and mouse game with another powerful witch. Summer Helsdottir has returned, and this time, she's hunting Wren. Meanwhile, a steadfast Kaito Miyazaki races to find his lover before another technomancer tracks her down. Ready to put everything on the line to reconnect with Wren and keep his witch from facing a second death, he's hot on her trail but always one step behind. Will he catch up before either a witch-killing technomancer, soul-eating curse, or dangerous creature turns his beloved to dust? Wren is counting on her disguise to keep her safe but with peril at every turn, she may need more than magic to escape her fate.
