Fair is foul and foul is fair ... bestseller Ross Montgomery returns with a laugh-out-loud, perfectly pitched introduction to Shakespeare's Macbeth.

Beth has been looking forward to the Prizegiving Assembly all year. She's won best-behaved pupil two years in a row and is confident that she'll triumph again for a third time.

But as preparations continue for the ceremony, which includes a performance of Macbeth by the drama club, Beth finds out that she's been pipped to the post by not one but two of her classmates, leaving her in third place.

Beth cannot bear to lose, so she channels her inner Macbeth and will stop at nothing to tarnish the reputation of her competitors. But as she puts her dastardly plans into action, she realises that villainy comes at a high cost!
