My Soul To Keep by Rachel Vincent
Kaylee has one addiction: her very hot, very popular boyfriend, Nash. A banshee like Kaylee, Nash understands her like no one else. Nothing can come between them.
Until something does.
Demon breath. No, not the toothpaste-challenged kind. The Netherworld kind. The kind that really can kill you. Somehow the super-addictive substance has made its way to the human world. But how? Kaylee and Nash have to cut off the source and protect their friends—one of whom is already hooked.
And so is someone else…
This was amazing! I don’t even know where to begin. It had so many twists and turns it never got boring. I was entangled into Kaylee and Nash’s life. The problems that she encountered in the last two book seems minuscule compared to what she has to face in this book as she learns more about the Netherwold and has to fight the evil force for those she love. Kaylee, was strong and did not let anything deter her from her what she believed in. Rachel Vincent creates a layered world paired with great characters to keep the plot moving and intriguing.
I just have to add, I can not wait for the next book! The ending was so..., I can't even formulate words to describe it but leaves you aching for the next book.
