The Blood Between Us

Growing up as the adopted sibling wasn't easy, but Adrien tried to get along; it was his sister, Grace, who didn't want anything to do with him. When their scientist parents died in a terrible lab fire, there was nothing left to hold them together.

Years late, Adrien and Grace must reunite for their senior year,at the elite boarding school where their parents taught. Being back causes Adrien to examine how he has changed, even while seeing Grace turns him into he doesn't want to be. But all this is cast aside when Adrien starts to suspect that Grace might be stealing their parents' research and claiming it as her own - or worse, that she had a hand in their deaths. Suddenly, the only questions that matter are whether she's guilty and, if so, what Adrien is going to do about it.
