From the Southbank Centre website:
"Imagine is the UK’s brightest and best children’s literature festival. Imagine 2009 features readings, storytelling, poetry, exhibitions, dance and music across Southbank Centre. There is a special installation, free performances and workshops on The Clore Ballroom in Royal Festival Hall."
There is so much, and a lot of it's free. Running from 12-22 February.
I'm sure my daughter would love to be there for launch of Cbeebie's Poetry Pie!
