The Emerald Atlas by John Stephens sounded a great youngsters read. The book jacket mentions affinity to books by CS Lewis, JK Rowling and Philip Pullman.
However, with its 'old leather book' and 'an ancient prophecy' it does sound very like Narnia.
A quick dip-in makes me think it reads well and I look for ward to reading it and reviewing it in the near future.
It's for 10+ and is a hardback at £12.99 and is release on 14th April.
