Southern California has run out of water; the taps have run dry and it is only a matter of time before chaos consumes the entire region. Alyssa and her family are your normal suburban, middle class family who are as surprised by the Tap Out as everyone. Luckily, they do live next door to Kelvin and his prepper family who are actually prepared for this eventuality. Alyssa and her brother Garret are struck by one tragedy after another as bad decisions and chaotic times work against them. They team up with Kelvin and Jackie to try and find water and survive the Tap Out. 

I loved the premise of this book because it is so realistic. California has been subject to droughts and water restrictions for years, so the water running dry is completely believable. As is the chaos that would ensue as people fight for what few resources remain. I thought FEMA's response was a bit questionable, but it added to the drama of the story. What I didn't like about the book was the main character of Alyssa and just how many terrible decisions she and everyone around her makes. These guys literally cannot catch a break throughout the entire story. At one point Alyssa gets so hung up on the fact that in 8th grade Kelvin used his drone to look in her window that she almost derails the entire venture to find water. I wish the characters could have been a bit smarter, but I guess dumb makes better storytelling.
