Second Time Lucky

Taylor's dad is sick. Very sick. Yet everyone around her doesnt seem effected by this at all.
This summer could be Taylors dads last, so her family is taking one last trip to their beloved lakehouse for the entire summer.
The only thing is she's terrifed of who she might run into again, they havent been back in 4 years and now shes 18. The last time they visited it didnt go well for her. All should go well if she doesnt run into him and his family.
Whats the worse that could happen.
