Four teenagers head off to Yosemite to go camping. Each has a different agenda and understanding of why they are there. Three boys from a prep school who said they were going to a tennis tournament and a girl who is a soccer super star. Sudden storms catch them off guard and isolate them from the world. A race begins agains time. Will they make it? Will anyone find them? Do they all survive? Further complicating things is the drama and blaming they dish on each other. This was a well written novel with a great cast of complex characters. Once I got about half way I couldn’t put the book down because I had to know what happened next. I highly recommend this book if you like thrilling adventure stories.
