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, The Monument. What they discover in the secret chamber beneath the floor leaves them speechless but desperate to know more.

A gripping adventure that makes us question whether another force has been at work for centuries 

The Spiral Staircase is the second book in the Lolloper series. Ideal for children aged 8 to 12 to read independently or together with a grown-up!
