Stargirl Academy 4: Ava’s Sparkling Spell [EPUB ebook] 

The girls in Team Starlight learn spells and earn their stars in this magical new young fiction series!Welcome to Stargirl Academy, the magical school in the clouds! Previously a rather old-fashioned establishment, it has been reopened by its head teacher to train children to be modern day fairy godmothers. Fairy Mary Mc Bee selects a group of girls: Lily, Ava, Madison, Sophie, Emma, Olivia — and Melody and Jackson who think they’re better than everyone else. The girls learn lots of spells — shimmering, starry, shining, sparkling, glittering and twinkling ones — which they use to fix problems and help people in trouble. For every successful mission they gain a star, and once they have six stars they will be fully qualified stargirls! It’s Lily’s turn to lead a mission but she hands over to Ava who is worried about her lovely local cafe. Cafe Blush is losing customers to a new place down the road and faces closure. The Stargirls investigate the new cafe and find it’s a sham — what’s more, the kitchen is disgusting! With a nifty sparkling spell, the girls expose the owners’ sloppy standards and everyone returns to Cafe Blush! Another successful mission — and another star!
