Emerging out of the pages of a super team comic, Faith Herbert (aka the Zephyr) emerges in a solo book. She's a pop culture blogger often at odds with her editor when she's not being a superhero. She's on the case when psiots (psychically powered heroes) start disappearing.
To be honest, there's nothing really special or unique about the plot of this book. Its pretty standard superhero fare. What makes is stand out is its lead character. Faith is likable and fun. In addition, the book uses a great amount of humor, and has some great heart.
While Faith came from the pages of Harbinger, you can read this book without having read the other series and understand things pretty well. Overall, a fun volume and I hope to read more in the series.
