Lively and then some, this comic for very young readers has a tigerish cat called Agent 9, who it seems never manages to pull off a mission without some disaster or other, and therefore starts this volume of his adventures on a last-chance probation. But there won't be a mission without some idiotic baddie and his robo-squid, and plans for flooding the world and making it a fun park for aquatic beasties (the name 'Waterworld' was taken…). The book's appeal does kind of depend on an enjoyment of the silly – the baddie is not alone in being daft, such as the implausible way our hero can understand every identical 'beoop' from his flying drone as an entirely different message. But the appeal is a broad one, on a par with the Saturday morning cartoons our creator has worked on in the past. The fact I saw it when it was over two years old and we've only had one sequel suggests the franchise didn't really take off, which was a surprise – there may be hundreds of books like this out there, but this was a friendly and enjoyable one, and for once not something so daft and gaudy people over a certain age were excluded.

Oh, and most reviews have the lead as a female, because yes there is no gender in this, although I can't help but feel some got confused about the word 'feline'. Don't hate me for thinking the thing is a male, though – it's certainly going to be over-thinking the whole book to discuss it much anyway.

Great action packed graphic novel about a hapless secret agent who can't quite help causing chaos on his missions. Brilliant for reluctant readers and bookworms.

This is a great new graphic novel series for middle grade (and slightly younger) readers with lovely illustrations, a good balance of text and a fun story.

Agent 9 is great character that I think a lot of children could relate to (a bit of a walking disaster!) - he always manages to complete his missions but often with lots of unintended (and quite funny) side effects so he has been put on probation by his managers. However, King Crab takes over their headquarters and so Agent 9 is the only one available to go and save the world.

Lots of adventure, lots of fun and an easy to follow story. Would be great for reluctant readers who enjoy a good story but who get overwhelmed by lots of text - this had the balance just right.

Well this was FUN! Action packed and filled with chaos and just the right amount of peril! Young readers are going to love this series. Definitely keeping an eye out for more!

I loved finding another one of these on Netgalley! Agent 9 has to learn to breathe and pause before acting here… because she destroys a lot and makes her job harder. The illustrations in this are gorgeous - so much colour, so vibrant, so fun. Definitely a go for KS1/LKS2 - will be trying to track down for school!

Meet Agent 9, the new spy kit in town and side kick, Fin the robotic fish. Agent 9 will stop at nothing to save the town from evil. No really, Agent 9 really will stop at nothing no matter how much cat-astrophy and mayham ensues. Children and grown ups will love this not so cool cat and the long suffering Fin. There is just the right mount of drama and peril with plenty of slap stick humour. I can't wait to recommend Agent 9: Flood-a-geddon to my new Book Pen Pals come September.
