Perfect Chemistry Series by Simone Elkeles

When Brittany Ellis walks into chemistry class on the first day of senior year, she has no clue that her carefully created “perfect” life is about to unravel before her eyes. She’s forced to be lab partners with Alex Fuentes, a gang member from the other side of town, and he is about to threaten everything she's worked so hard for—her flawless reputation, her relationship with her boyfriend, and the secret that her home life is anything but perfect.

Alex is a bad boy and he knows it. So when he makes a bet with his friends to lure Brittany into his life, he thinks nothing of it. But soon Alex realizes Brittany is a real person with real problems, and suddenly the bet he made in arrogance turns into something much more.

In a passionate story about looking beneath the surface, Simone Elkeles breaks through the stereotypes and barriers that threaten to keep Brittany and Alex apart.

When Carlos Fuentes returns to America after living in Mexico for a year, he doesn’t want any part of the life his older brother, Alex, has laid out for him at a high school in Colorado . Carlos likes living his life on the edge and wants to carve his own path—just like Alex did. Then he meets Kiara Westford. She doesn’t talk much and is completely intimidated by Carlos’ wild ways. As they get to know one another, Carlos assumes Kiara thinks she’s too good for him, and refuses to admit that she might be getting to him. But he soon realizes that being himself is exactly what Kiara needs right now.

Luis Fuentes is a good boy who doesn't live with the angst that his big brothers, Alex and Carlos, have always lived with. Luis is smart, funny, and has big dreams of becoming an astronaut. But when he falls for the wrong girl, Luis enters a dark world he's never known, and just when he thinks he's got life all figured out, learns some disturbing news about his family that destroys his positive outlook on life. Will that Fuentes bad boy streak come out with a vengeance and lure Luis to live on the edge like his new girlfriend and his own father?
Continuing all the steamy romance of the first two books, New York Times and USA Today bestselling author Simone Elkeles gives fans one more satisfying taste of the irresistible Fuentes boys.
