Books in Hollow Earth series

In this fresh and innovative middle grade fantasy, imagination matters most in a world where art can keep monsters trapped—or set them free.Lots of twins have a special connection, but twelve-year-old Matt and Emily Calder can do way more than finish each other’s sentences. Together, they are able to bring art to life and enter paintings at will. Their extraordinary abilities are highly sought after, particularly by a secret group who want to access the terrors called Hollow Earth. All the demons, devils, and evil creatures ever imagined are trapped for eternity in the world of Hollow Earth—trapped unless special powers release them. The twins flee from London to a remote island off the west coast of Scotland in hopes of escaping their pursuers and gaining the protection of their grandfather, who has powers of his own. But the villains will stop at nothing to find Hollow Earth and harness the powers within. With so much at stake, nowhere is safe—and survival might be a fantasy.

Matt and Emily Calder’s travels through time come to a thrilling conclusion in the third book of the Hollow Earth trilogy as the siblings struggle to close Hollow Earth—and keep the monsters inside.Twins Matt and Emily Calder may be divided by time, but they are united in their mission to close Hollow Earth before the monsters inside can destroy the world. The key to success lies with their Animare talents: they can draw things into life and travel in time through art. But there are monsters outside Hollow Earth as well. Monsters intent on taking control of the beasts for themselves. And the worst monster of all is their own father…

In this thrilling sequel to Hollow Earth, Matt and Emily must stop someone from unleashing an army of mankind’s worst nightmares.In the Middle Ages, an old monk used his powers and a bone quill to ink a magical manuscript, The Book of Beasts. Over the centuries the Book, and the quill, were lost. Twins Matt and Emily Calder are Animare—just like their ancestor, the monk. The things they draw can be brought to life, sometimes with disastrous consequences. Now Matt and Em are being watched—hunted—because only they can use The Book of Beasts and the bone quill to release the terrible demons and monsters their ancestor illustrated. And someone is tracking down the lost Book of Beasts, page by page, and reassembling it. Matt and Emily have no choice: They must get to the bone quill first…before somebody gets to them.
