*Though three hundred years have passed since Alexi's death, Vogelein finds herself still haunted by the unkept promise she made to her first Guardian. *Now the clockwork faerie must confront her past with the help of Mason, an itinerant musician whose spirit bears a striking resemblance to the one she desperately wants to lay to rest. As she struggles to find peace for both herself and Alexi, Vogelein discovers that centuries-old questions rarely have easy answers, intended paths reveal themselves in mysterious ways, and present-day threats strike just as suddenly as those from long ago.
