A Tale of Two Giants — Scott William Carter

You don't have to be tall to be a giant.
They meet on a rainy night, penniless and alone, both of them without a friend in the world. He's a disgraced, down-on-his luck giant, short for his kind, banished forever from his tribe. He just wants to be left alone - and pity the poor person who annoys him.
She's a stubborn human girl whose mother has been kidnapped by an evil dictator - and she's determined to get her back. No matter how long it takes. No matter who gets in her way.
Together they take on an empire.
"Grade 4-9;" In this intriguing fantasy about two outcasts on a remarkable journey, Carter offers up a riveting adventure that should appeal to fans of J.K. Rowling's Harry Potter series or Rick Riordan's Percy Jackson books. Although this book stands on its own, readers may want also want to try Carter's first foray into his Lost Lands of Rymadoon series, Drawing a Dark Way.
