Sam Waver's life has always been pretty quiet. A bit of a loner, he struggles to make friends, and his busy parents often make him feel invisible.

Luckily for Sam, his older brother, Jason, has always been there for him. Sam idolises Jason, who seems to have life sorted - he's kind, popular, amazing at football, and girls are falling over themselves to date him.
