Reviewed by Katelyn Hensel for Readers' Favorite Time Hackers by Layne Walker is a middle grade to early teen book with elements of science fiction, time travel, fantasy, and the general pre-teen angst that we've all come to know and love in middle grade fiction. Sixteen-year-old Jeff Watson is shaken out of his normal teenage happenings one day when he comes face to face with a dinosaur in his kitchen. A triceratops to be exact. And if you think you'd be prepared to find anything in your house, just wait until you find yourself looking at three long and pointy horns staring you down. Jeff's brothers say that they brought their new pet home from the past. They've built a time machine and the triceratops accidentally came along for the ride when they went home. Jeff, like any logical person on this earth, doesn't believe them...but there's nothing like 5 tons of proof sitting in your living room! Jeff gives the time machine a try and ends up trapped in a world that our current time of technology and international connections forgot. Now Jeff and his brothers have to survive the dangers of this prehistoric jungle in order to get home, but that's not the only problem facing the brothers. Turns out the government caught wind of the machine and now they've sent an agent to acquire it...leaving the boys stranded. This was a good old fashioned action adventure book. Akin to Journey to the Center of the Earth and others of the same ilk. I really enjoyed it and expect my 12-year-old nephew to be really into it as well.
