Completely Cassidy - Accidental Genius

With my embarrassing Dad, pregnant Mum, loser brother and knicker-chewing dog, I'm practically invisible in my family. So even though starting Year Seven is totally nail-biting, I'm *hoping* this is my time to shine. Because guess what?

We had to take this test at school, and I am officially Gifted and Talented. It's a bit weird as I picked my answers at random, but the school wouldn't make a mistake about my genius... would they?

“Perfect reading for any youngster suffering from big-school nerves.”
Lancashire Evening Post
“Witty, fresh and heart-warming.”

The Completely Cassidy series is an absolute delight: with bonkers family descriptions and dynamics a la Georgia Nicholson, and the terrific combination of genuine warmth and hysterical writing, I found myself laughing out loud constantly.

Girls from 9+ will enjoy this and will be looking out for a sequel.
Books for Keeps
There are rumours of Deputy Heads twerking... fall outs between friends, new sibling arrivals and first crushes – the perfect ingredients for 8+ years readers wanting a witty, fresh and heart-warming story.
Tamsyn Murray writes with flair, imagination and, one would imagine, with a big smile on her face as Cassidy’s laughter-filled life spring into glorious action. Perfect reading for any youngster suffering from big-school nerves.

Sweet, fun and completely adorable. I can’t wait to read more of
the Completely Cassidy series!

So Many Books, So Little Time
For fans of Wimpy Kid, Cathy Cassidy and books of that ilk, this is a story that readers will enjoy very much... a great tale for the pre-teen market.
