Conjuror: Orion Chronicles

The first in a new YA sci-fi series from the brother and sister writers, this follows on from the "Hollow Earth" series and features the same central characters, twins Matt and Em Calder, who are now 16. They can bring art to life, and travel in time through paintings. John Barrowman has worked in TV, musical theatre and film, and played Captain Jack Harkness in "Doctor Who" and "Torchwood". His sister Carole E. is a talk show host and teacher. *Also appeared in April Buyer's Notes*
