Space Boy Volume 5 (Space Boy, #5) by Stephen McCranie

A sci-fi drama of a high school aged girl who belongs in a different time, a boy possessed by emptiness as deep as space, an alien artifact, mysterious murder, and a love that crosses light years.

To Amy, everyone has a flavor, and when that flavor begins to disappear, it spells trouble.

After the crushing confrontation with Oliver, Amy is on the hunt for answers. This leads her to an old, moldy water containment facility, and leaves her with more questions than answers. At the same time, some of Amy's closest friends may be drifting apart.
