Ruby Rogers is about to turn ten. She wants to be a gangster when she grows up. She also wants nothing more than a tree house for her birthday. Problem is, there aren't any trees in her garden, and her family laugh off the idea. Ruby's furious, but then life takes a turn for the better when, through her best friend Yasmin, she meets Holly Helvellyn, a super-cool Gothic girl who's friends with Yasmin's older sister. It turns out Holly rather fancies Ruby's older brother Joe - the brooding a...

Ruby's mum is sick . . . or is she? It's very upsetting when your parents don't tell you what's going on. And Ruby's not the only one who's upset. Yasmin gets a nasty shock when someone sends her an anonymous email.Fortunately Holly Helvellyn, Goth teen idol and generally Miss Amazing (except for that miserable boyfriend she now drags around), is on hand to cheer Ruby up, but even she doesn't have the answers to everything. The truth will out eventually, though . . .

Ruby's off to the seaside with Mum, Dad and Mum's work friend Deb and her family. It's soon clear that Ruby and Sasha, Deb's daughter, have absolutely nothing in common, so when Sasha does decide to take a sudden interest in monkeys in an evil attempt at one-upmanship, this can mean only one thing: REVENGE.It's a good job Dad wants to teach Ruby to swim, as it gives them both an escape from Sasha and her family. Well, it would be a good idea if he didn't almost drown her!

Winter is closing in, and with it comes a new set of problems. Ruby is afraid of the dark, and older brother Joe enjoys taking advantage of this by giving her scares whenever he can. The fabulous Holly points out that everyone is afraid of something. True as this turns out to be, it doesn't really help Ruby, especially when she discovers that her babysitter is even more afraid of the dark than she is!On top of that, it's the school play and Ruby also has to confront her stage frigh...

Hi! I’m Oliver Tibbs (some people call me 'Oliver Fibbs') and sometimes my life gets a little DAB - Dull And Boring. So from time to time I 'get creative' with the truth at Show and Tell. Although I honestly am a Defender of Planet Earth, just like Agent Q in my favourite comics, and right now my uncle, the world-famous explorer, Sir Randolph, is lost in the Antarctic and it’s up to me to find him. Plus a new ice age is about to freeze the Earth unless I find a way to stop it – there are e...

But I'm fighting back with a mega robot of my own!OK, maybe I'm exaggerating . . . but as...
