I've wondered how powerful Chase truly is so I was excited about his story. His abilities are definitely all that, but actually, his vulnerability is at least as attractive. He's been starved for affection for so long. It's astonishing that he became such a great man. As much as this is a high-action battle between the good and bad sides of the psy community, it's a love story between Chase and Elijah. Both have been through enough pain for a lifetime. Their resilience is amazing. Chase has some stunning displays of his psy talent in this book. I love that he uses it for protection and not to lord over everyone else. If you want action or romance, Sightlines delivers. It is a fitting ending to the series, but I can also see how more books might be added some day.
