A psychological thriller about a night of babysitting that turns fatal and a girl determined to figure out if the gas leak was an accident, perfect for fans of E. Lockhart's We Were Liars.

Ella was supposed to have fun night with her friends until a crippling headache tied to a recent diagnosis cancels her plans and leaves her babysitting her cousin instead. 

But when she arrives at the house, she immediately knows something is wrong. The lights are off and the door is wide open. But it’s the creeping smell coming from the house that warns Ella of the real danger inside: a gas leak. 

In a panic, Ella charges into the house and calls 911. Her aunt and cousins lie unconscious on the floor—and Ella can’t rescue them all. 

As Ella tries to recover from the tragic accident, deadly lies begin to seep through the cracks of the investigation, and Ella’s side effects escalate. She’ll soon discover the gas leak might not have been an accident after all—and that someone might be out to kill her next.
