Limitless (Limitless #1)

Knox appears to have the perfect life. He lives on the beach in sunny, southern California He’s a photographer, and a father to an intelligent little boy, but not everything is as it seems. Underneath it all, Knox lives a lonely life, filled with meaningless moments that only seem to dissipate during the 60 minutes he spends with his son every day. Then one day he meets Emery Jane. Suddenly, the void of loneliness disappears. The only problem is Knox holds a secret, one that could crush the promises of a future with the one woman he has grown to love, and the son he would do anything for.
Six years ago, Emery Jane ran from the secrets that were buried six feet under and from her own living, breathing, nightmare. Emery Jane longed for a life of normalcy and living in paradise seemed like the perfect place to find it. She never expected to meet Knox and his beautiful little boy, and she certainly didn't expect to love them so fiercely. As she embraces the unexpected, Emery Jane thinks she can finally see the light at the end of the tunnel, which shows her that life doesn't always have to be so disheartening. But Emery Jane knows that with secrets come destruction, and that destruction is knocking on her door.
