There's a new girl in town, and Mia tries to take her under her wing. But Olivia Allen is not so nice; as a matter of fact she might be even meaner than Sydney Whitman! She asks Mia to lend her money, and even though Mia has been saving for weeks for a new pair of shoes, Mia lends it to her, only to find out that Olivia has used the money to buy the exact same shoes Mia has been saving up for! Plus she makes fun of the other Cupcake girls and tells Mia she shouldn't be friends with them. Will she wreak havoc on the Cupcake Club before Mia sees her true colours?
Coco Simon always dreamed of opening a cupcake bakery but she's afraid she would eat all the profits. When she's not daydreaming about cupcakes, Coco edits children's books and has written close to 100 books for children, tweens, and young adults, which is a lot less than the number of cupcakes she's eaten. Cupcake Diaries is the first time Coco has mixed her love of cupcakes with writing.
