“Hollow Earth”
by Carole E. & John Barrowman

About the Book

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 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.

About the Authors

The Barrowman siblings were born and raised in Scotland, moving to America in the late 70s. Carole is a long-time Wauwatosa resident and Professor of English and Director of Creative Studies in Writing at Alverno College. She also writes a newspaper column for the Milwaukee Journal Sentinel and lots of other publications. Twice a month she chats about books on WTMJ4’s “The Morning Blend.”

Carole’s wee brother, John, is an actor, singer and entertainer most famous for his television role as Captain Jack Harkness, whose first appearance on “Doctor Who” created such an impact that he was given his own spin off series, “Torchwood.” He currently appears on the CW series “Arrow.”

This is their sixth book together. For more about the book and the authors, go to
