Alejandro Molina is perfect on the outside; he's the smart, gorgeous, and wealthy child of a famous supermodel. All of his many flaws are inside of him instead, where no one can see them until it's too late. His life is marked by roaring highs and echoing lows, both of which went unexplained until this summer-when he was diagnosed with Bipolar I disorder. With this information and a moving van full of baggage, he's ready to flee to Stanford so his worst traits and biggest insecurities can no longer haunt his life. Jordan Dawson has been Alejandro's other half since they were born-albeit a whiter, richer, and meaner one. Held like a puppet on strings by the centuries-old wealth of his family, he once found refuge in Lillian, the love of his life. Until she disappeared, that is. Two years after their last summer together, he's still picking up the pieces with another chip on his shoulder: the fact that he might love Alejandro as more than a friend now-and the fact that it will never happen. He applies to Stanford and follows his best friend to the other side of the country, but what he finds there presses reset on more than one of his relationships...in more than one way. Lillian Bennett has spent the last two years on the California coast with her family, putting herself back together after a suicide attempt and the biggest adjustment of her life. Her identity revolves around her ambition and smarts, so who will she become when a random accident sets off a chain reaction that she can't control, or even notice? Why is her ex-lover Jordan at Stanford? And why is her childhood rival Alejandro being so nice to her after years of ignoring her existence? She doesn't want either of them, right? Right? Keyframe revolves around the lives of three teenagers toeing the line between childhood and adulthood, testing their intelligence, and learning when to keep trying or to move on. Their lives are intertwined now-and they were before they even knew it themselves.
