On the outside, seventeen-year-old Madelyne Summers looks like your typical blond cheerleader—perky, popular, and dating the star quarterback. But inside, Maddie spends more time agonizing over what will happen in the next issue of her favorite comic book than planning pep rallies with her squad. That she's a nerd hiding in a popular girl's body isn't just unknown, it's anti-known. And she needs to keep it that way.Summer is the only time Maddie lets her real self out to play, but when she slips up and the adorkable guy behind the local comic shop's counter uncovers her secret, she's busted. Before she can shake a pom-pom, Maddie's whisked into Logan's world of comic conventions, live-action role-playing, and first-person-shooter video games. And she loves it. But the more she denies who she really is, the deeper her lies become...and the more she risks losing Logan forever.

Suelette Dreyfus and her co-author, WikiLeaks founder Julian Assange, tell the extraordinary true story of the computer underground, and the bizarre lives and crimes of an elite ring of international hackers who took on the establishment. Spanning three continents and a decade of high level infiltration, they created chaos amongst some of the world's biggest and most powerful organisations, including NASA and the US military. Brilliant and obsessed, many of them found themselves addicted to hacking and phreaking. Some descended into drugs and madness, others ended up in jail. As riveting as the finest detective novel and meticulously researched, Underground follows the hackers through their crimes, their betrayals, the hunt, raids and investigations. It is a gripping tale of the digital underground.

From New York Times bestselling author Sam Kean comes incredible stories of science, history, finance, mythology, the arts, medicine, and more, as told by the Periodic Table. Why did Gandhi hate iodine (I, 53)? How did radium (Ra, 88) nearly ruin Marie Curie's reputation? And why is gallium (Ga, 31) the go-to element for laboratory pranksters? The Periodic Table is a crowning scientific achievement, but it's also a treasure trove of adventure, betrayal, and obsession. These fascinating tales follow every element on the table as they play out their parts in human history, and in the lives of the (frequently) mad scientists who discovered them. The Disappearing Spoon masterfully fuses science with the classic lore of invention, investigation, and discovery -- from the Big Bang through the end of time. Though solid at room temperature, gallium is a moldable metal that melts at 84 degrees Fahrenheit. A classic science prank is to mold gallium spoons, serve them with tea, and watch guests recoil as their utensils disappear.
