Hollow Earth by John Barrowman and Carole E Barrowman
Lots of twins have a special connection – being able to finish each other’s sentences; sensing what the other is thinking; perhaps even knowing when the other is in trouble or in pain – but for 12-year-old twins, Matt and Emily Calder, the connection is beyond special.
Together, the twins have extraordinary powers – they are Animare: able to bring art to life, or enter paintings at will. Their abilities are sought by villains trying to access the terrors of Hollow Earth – a place where all the demons, devils and evil creatures ever imagined lie trapped for eternity.
The twins flee with their mother to the security of Auchinmurn Island, off the west coast of Scotland, where their grandfather has certain protective powers of his own. But too much is at stake, and the twins aren’t safe there either. The villains will stop at nothing to find Hollow Earth and if Hollow Earth is breached, the world will be plunged into chaos. If Hollow Earth is breached…
The twins are as good as dead.
