Ten Seconds Too Late

History is repeating itself in the most horrific way.
I never wanted to hurt Elena. Being my best friend's little sister, I knew falling for her would be life-changing. Yet the first time we kissed, something shifted inside of me. I knew without a shadow of a doubt I would give my life to protect her.
Then I began to notice disturbingly familiar trends.
Pulling away.
Distancing herself from everything and everyone.
Frequent panic attacks.
This was the same pattern my sister slipped into before her suicide. I thought the passion between Elena and I would be enough to pull her through. But things are happening in her mind she can't explain, leaving me terrified for her well-being.
I need to keep her safe, even as she pushes me away. Doing so means delving into the past to uncover dark truths buried deep. Can I untangle the web of lies surrounding us? Or will my failure cost Elena her life?
