The Spiral Staircase by Ian McCartney

How far would you go to help your friend even when they might not deserve it? 

A school trip to The Natural History Museum in London turns into a breathtaking adventure for twins, Sam and Olivia, and their best friends Charlie and Natalie. Threatened by the Grimper as they attempt to unlock the mysteries of the Eternal Cycle, their friendship is tested to the limit and their fight for survival takes them to the scene of one of the most devastating events in London’s history. What they discover leaves them speechless but desperate to know more.

Ideal for boys and girls aged 8 to 12, The Spiral Staircase is the second book in a riveting new adventure series that proves it’s the small things that make the biggest difference!

You may never look at the world in the same way again?

Described by a leading book critic as “The ‘famous five’ for today’s kids!” 

If you want to read The Lollopers series from the start, then look for book 1, The Eternal Cycle – and look out for the release of book 3 later this year, The Fairy Steps.
