My Soul to Keep by Rachel Vincent

My Soul to Keep (Soul Screamers, Book 3) brings us back to the world of Kaylee Cavanaugh, teen-aged bean sidhe.  Kaylee, still adjusting to life with her recently returned father, is finally finished with her grounding from her last adventure when the Netherworld rears its ugly head in her home town.  It appears that some of the students in her school, friends of Nash, are inhaling Demon's Breath for a high, unaware of its otherworldly origins or of its deadly consequences.

Kaylee and Nash set out to protect the student body from the highly dangerous Demon's Breath, but all is not as it seems.  Nash's behavior is erratic and he keeps trying to Influence Kaylee.  Both Emma and Sophie are wrapped up in things via their respective boyfriends, and Kaylee can't know for sure how much danger either of them are in.  She wants to go to the adults for help but Nash keeps stopping her.  The whole story seems a bit disjointed before things finally click into place for Kaylee and, vicariously, for the reader.  Once the core of the story begins to unwind, we see that all roads lead to Avari, the hellion whose attempt to snatch Kaylee's soul was thwarted in My Soul to Save (Soul Screamers Book 2).  I won't tell you how things develop to this point, but once Avari is revealed, things begin to make a little more sense and the action begins to pick up.  Kaylee must make some difficult choices and take a long, hard look at who is truly on her side.

In My Soul to Keep (Soul Screamers, Book 3), Kaylee begins to grow up.  She has to make difficult decisions based on what is right, not on what she wants.  She also seems to have made an enemy in Avari, bringing Netherworld into her life on terms other than her own.  Her actions in previous books are coming back to either benefit her or make her re-evaluate the consequences of her previous decisions.  Overall, I think that this book represents a turning point in the series.  Kaylee is maturing, the problems are getting bigger and the villain is badder.  It seems as if the character relationships will be more complex in the coming stories which will benefit the series' longevity.
