Princess Amelia Mignonette Grimaldi Thermopolis Renaldo's (or just Mia to her friends) diaries have reached their fifth instalment, and while admittedly it is more of the same as the previous books, there is also plenty of room for the characters to develop. As her fifteenth birthday approaches, we watch Mia grow to realise her gift for writing, wrestle with the torment of her boyfriend's unwillingess to go to his senior prom and become a big sister. The other characters get a look in too - Lily Moscovitz reveals her inner minx, Tina Hakim Baba turns into a modern-day Jane Eyre and even Boris Pelkowski displays a surprisingly passionate nature. The books still keep you hooked as you smile, laugh and cry along with Mia and her buddies, but I still couldn't shake the feeling of deja vu. You could do worse than spending a few hours reading this, but it isn't exactly a classic. The first three are a lot better.
