Alcatraz vs. the Evil Librarians - Brandon Sanderson

AN ANCIENT RIVALRY REAWAKENS.Everything I'd known about the world was a lie.On my thirteenth birthday, I, Alcatraz Smedry (yes, I got named after a prison, don't ask) received my inheritance: a bag of sand. And then I accidentally destroyed my foster parents' kitchen.It's not my fault, things just break around me, I swear!I thought the sand was a joke until evil Librarians came to steal it. You're probably thinking, "Librarians are nice people who recommend good books," but that's just what they want you to think! It turns out they're actually a secret cult keeping the truth from you-a hidden world filled with magical eyeglasses, talking dinosaurs, and knights with crystal swords!Or so my Grandpa Smedry claimed when he suddenly showed up to rescue me. So now I have to go with him to invade the local library and get that sand back, before it's used to conquer the world.And Grandpa says how I keep breaking things is actually an amazing talent. There's no way that can all be true, right?Will I ever make it back home alive?
