An uneasy truce is being held between Sally's devil, Muddlespot, and her angel, Windleberry. But then the cupids attack . For once, Muddle and Win are in agreement: cupids mean Trouble. They both know that when True Love is involved, things aren't simply black or white - they're horribly, confusingly pink! Sure enough, a heart-tipped golden arrow makes Sally's sister Billie fall for Tony, the hottest, and most off-limits, boy in school. War breaks out at Darlington High, and as usual it's up to Sally to put things right. But can she undo the damage without getting caught in the crossfire?.
