Press reviews

“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.”
“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.”
“Tamsyn Murray has a real talent for seeing the funny side of the everyday.”
“Sweet, fun and completely adorable. I can’t wait to read more of the Completely Cassidy series!”
“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.”
“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.”
“Girls from 9+ will enjoy this and will be looking out for a sequel.”
