I hated giving this three stars because there were several things I really liked about this book. I loved the characters. Jack was a single father. He'd once been on the road to becoming a major league baseball star when an accident while driving drunk put an end to that career. Then his son was diagnosed with diabetes. As a result, Jack's wife, Lauren, walked out on Jack and Andy, never to be seen again. Now Andy is in high school, attending the private school where Jack works as the janitor. Jack is also in a relationship with Ellie, a local police officer. They are taking things slow although Ellie is having a hard time figuring Jake out at times. She's never been to his house. Whenever they get together it's at her place. He's also very close mouthed regarding his past. She really wants to know him so she Google's him and finds out about his lost baseball career.
Jack is a little upset about it at first but realizes Ellie has a right to know if they are going to continue seeing one another. However, there's something Ellie still doesn't know, a secret Jack is afraid to reveal for fear it really would destroy what they have at the moment. He's a prepper. He believes totally in the whole world is going to end scenario or the possibility the United States will be attacked by foreign enemies. He's prepared and taught his son what to do in case something happens. As janitor at the academy where he works, he's got total access to the tunnels running underneath the school and has stored up everything he and Andy could possibly need when doomsday comes. Weapons, food, water, a heat source, first aid supplies, etc. There's enough to last them for a long time. He even wakes Andy at 3 am to run a drill where they rehearse all kinds of potential threats that could occur.
Andy is getting tired of it. His dad has gotten obsessed and Andy has other things to worry about now. He and his friends at school started a secret group called The Shire. All of them are very smart and a couple of them have unbelievable computer skills. They began hacking into some of their wealthy classmates' parent's investments, stealing money, and donating it to various charities. They get away with it for a time but then really mess up when they steal a huge amount from a big drug cartel. Of course, the cartel wants their money back and they send several members to retrieve it. When they hatch a plan to evacuate the school, they then take the members of The Shire hostage intending to torture them until they get their money back. Jack is the only one who seems willing to do anything about it and knowing the tunnels like he does and with his stockpile of resources, he sets about rescuing his son.
The elements of action and suspense were all here. I had no problem with that. The torture scenes were a little disturbing but I got to where I skipped over those parts which took nothing away from the plot itself. I did have a problem with all the computer jargon and the talk of bitcoins, something I never heard of and didn't understand. This did detract from the story for me. I would think anyone who wasn't knowledgeable in this field might feel the same. I also wasn't thrilled with the whole drug cartel and speaking in Spanish, which had to constantly be translated. This slowed things down.
Have you ever read a book and at the end you liked the promise of something entertaining at the start but once finished you were left with the feeling it was somewhat lacking but could have been so much more? That's the way I felt at the end. I loved the plot, loved the characters, but at the end was left disappointed and thinking it could have been so much more.
