Sam thought, “What ordinary kid knew all about detonators and plastic explosives? What ordinary kid wasn’t even surprised when a tourist pulled out a gun, and a helicopter full of bad guys showed up?” –The Eureka Key
The Eureka Key
Secrets of the Seven #1
by Sarah L. Thomson
When middle school puzzle master Sam and history wiz Martina win a contest for a summer trip across the U.S., they discover they’ve been drafted into something vastly more extraordinary. Joining another kid on the trip, Theo, a descendant of George Washington himself, they must follow clues to find seven keys left behind by the Founding Fathers.
Together, the keys unlock Benjamin Franklin’s greatest invention – a secret weapon with the intention of defending the country. Each key is hidden in a unique location around the U.S., protected with puzzles, riddles, and traps. This has kept the weapon safe . . . until now! Gideon Arnold, a dangerous descendant of the infamous Benedict Arnold, is on the chase.
Readers of The Eureka Key will enjoy learning about one of America’s founding fathers, Benjamin Franklin, in this fast-paced story. The action begins from the very first page and never stops. To find a weapon hidden by the Founding Fathers, Sam, Martina and Theo must find clues and answer the riddles left by Benjamin Franklin. With the villain’s goons just steps behind them, the kids must focus on deciphering the clues. Similar to Indiana Jones and the Temple of Doom, each new clue can also lead to a potentially deadly trap which makes for some very suspenseful moments. The clues are based on Franklin’s real inventions and readers will attempt to figure out the clues along with the characters.
While the action drives the plot, both Sam and Martina are well-developed but imperfect characters. Girl Scouts has taught the nerdy Martina to always be prepared, and her quirks make her very likable. At first, Sam laughs at everything Martina packs and teases her for her encyclopedic knowledge, but Sam soon realizes that without Martina he wouldn’t have survived the journey. Sam begins as a reckless troublemaker, but after the near-death journey, Sam asks himself, “So which Sam Solomon was he? The one who hacked into school computers to change his friend’s grades, or the one who did his best to save the country from treachery that went back more than two hundred years?” In the end, Sam’s character growth and maturity will please and surprise readers.
The Eureka Key will appeal to a wide range of readers. Those who love mystery, puzzles, history, and action will enjoy The Eureka Key. Even though the story has many historical facts, they are integrated into the story, and they never read like a history textbook. Some of the characters are descendants of historical figures and one character is a descendant of Benedict Arnold. While some believe Arnold was a traitor, his descendant reminds readers, “History sometimes forgets the truth.” Readers interested in learning more about Benedict Arnold should read George Washington’s Spies by Claudia Friddell. The characters, mystery, and history combine to make a highly entertaining story that will have readers reaching for the next book in the series, The Eagle’s Quill.
- A man who Sam calls “Aloha” kidnaps Sam, Martina, and Theo. Sam tries to leave clues for others to follow. “A second later, the loudest sound he’d ever heard nearly split his eardrums open. He yelped, and Martina jumped about a foot. . . Aloha was standing behind them with his gun pointed at Sam’s hat, which lay on the ground with a smoking hole through the brim.”
- Several times someone points a gun at the kids to force them to comply with orders.
- To find the eureka key, the kids must answer riddles. If they answer incorrectly, a deadly trap awaits them. While trying to figure out a clue, the kids make a mistake and, “The light around them seemed to flare, and Sam stumbled back, blinking madly. . . Then a scream filled the air. It came from Aloha. . .The orange flowers on Aloha’s shirt burst into red flames. He howled in pain, staggering across the plateau, as the fires took hold.”
- As Aloha is flailing, “Aloha was still holding his gun; it swung toward Theo as the man twisted and wailed. Theo dodged to the side as a bullet cracked in the air, and at the same moment Aloha’s left heel vanished off the edge of the cliff. He toppled and was gone, his screams lengthening.” Aloha dies.
- The villain, Flintlock, pulls a gun on the kids. When the kids open a secret door, “Theo snapped upright, driving a fistful of rocks into the man’s stomach.” Theo and Martina run, but someone has a hold on Sam. Then, “Something whizzed past Sam’s face, and then Martina’s flashlight cracked his captor right on the bridge of his nose. The hand around Sam’s arm loosened as the man howled.” The kids escape.
- To escape a trap, Martina connects an electrical circuit to herself. “Martina’s body shook as if she were a puppet with a madman yanking at the strings. . . Martina dropped to the floor as if the puppeteer had tossed her away and lay there—still as death.”
- The bad guys and the kids are in a room that has a lot of keys hanging from the ceiling. One of the bad guys, Jed, “grabs a key. Sam was sure he could hear electricity leaping from the key to Jed’s hand. The instant his huge fist closed around the key, he was flung across the room, so quickly he didn’t have time to cry out. He crashed to the floor and lay still.”
- Sam tries to sneak away from the bad guys. Sam “took two steps toward the way out, only to have a bullet blast into the wooden floor in front of him.”
- A man falls into a mine shaft. “There was a sharp, panicked yell that started loud and got softer and softer. . . until it stopped.” The man dies.
- During the revolution, Benedict Arnold left one of his contacts to be hanged.
- One of the villains slaps “Theo across the face. . . Theo stood as solidly as a deeply rooted tree and didn’t make a sound.”
- To get Sam to comply, one of the thugs grabs Martina. “He grabbed hold of her arm, clamping his other hand over her mouth and nose. He grinned as she made a startled, choking sound.”
- When Sam makes a smart-aleck remark, “the back of Arnold’s hand smacked into the side of his face.”
