Parasyte 2  by Hitoshi Iwaaki. In this second volume of the body-snatching horror manga, Shin finds out that his parents have been attacked while on vacation. Taking time off school to investigate, he strikes up an uneasy friendship with a local girl and finds another human who is infected but not overtaken. There's plenty of action and gore, and new demonstrations of the parasyte's abilities as Shin struggles with his own humanity. This is a thoroughly enjoyable series, and I eagerly look forward to volume 3.
