Showing results for "The Machine" in Mystery & Suspsense

Third-grader Aven Green has been solving mysteries for a really long time—a whole month! She has solved many important cases like The Mystery of the Cranky Mom, The Mystery of the Missing Ice Cream, and The Mystery of the Smelly Feet. Her record is nearly 100 percent, with only The Mystery of the Cereal in My Underpants remaining unsolved to this day. Aven asks all the right questions, wields her detective kit carefully, and follows up on every clue. Then her teacher’s lunch bag, with her lunch still in it, is taken, and Aven’s great-grandma’s beloved dog goes missing.

The physicist mother of Kizzy and Fraser Rye has invented an amazing time machine that can travel back into the past, snatch a plant or animal now extinct, and bring it back into the present. It's a wonderful achievement, a real scientific breakthrough. But the machine has a horrifying potential.
